Does initiative effect both the order units go in and how often a unit acts?

Making the faster units do less damage and the slower units do more damage seems to be a fairly common balancing trick.

Multi-attacks combined with being able to attack twice in a turn may need some consideration.

I'm using an initiative based turn system. This means that rather than each side having a turn in which it can move all its units, the units themselves will get a turn based on some initiative score. Faster units will, over the course of a battle, get more turns than slower ones (this will be balanced in various ways).

How do you intend on messaging this? It feels like it could be confusing.

The best implementation of a related system I've seen would be in Radiant Historia. I recommend you have a look if you're not familiar with the title.

I intend to do a lot with having different types of maps with different goals and victory conditions. I also wish to vary size and scope of battles. Some will be on small maps and the player will be able to use ~4-5 units. Others will be much larger and allow 10+ units.

You haven't specifically discussed the actual tactical ramifications of your gameplay. Are there advantages to flanking, positionning, terrain elevation, etc? How do you tie terrain with your attacks? Its good that maps will differ in party scope, but to make things fresh, its important to have terrain that matters, and not just for movement (though it helps).

A Unit, on its turn, gets 2 actions. These actions can be used to move, attack, move twice, attack twice, use an item, etc. I'm not against having special rules to balance things out if they seem overpowered. Perhaps a second attack would carry a penalty, for example. This will be tested and dealt with appropriately.

I've been toying with a tactical game myself for a number of months now. In the end, I had to rule out that the unit could either move-attack, attack-move, or move-move, but it could never attack-attack for balancing reasons. If you DO manage to have this work without introducing an arbitrary rule (such as the second attack being weaker) do let me know how you've achieved it.

The things a unit can do will be somewhat standard for the genre. A unit will have a regular attack, some selection of special skills with various effects, and so on.

Will special skills cost an 'action' (move or attack?). I like the complexity of Descent: Journeys in the Dark in that regard, but the action points economy is not all that straightforward.

I intend to make damage as deterministic as possible, with little/no randomization. Attacks will always hit, and the amount of damage dealt will be transparent and knowable to the player.

So, essentially, its more strategy than rpg then? Will you be employing an armor-like mechanic for defense where damage is reduced? If so, how do you plan to break potential stalemates where defenses have gotten too high for regular attacks to pierce? (That's generally where random comes in handy, hence my asking).

Intelligence, Speed, Cleverness

Intelligence, I assume, for magical attacks.

Speed, for movement on the map?

Cleverness... no clue :)

Make all damage dependent on the appropriate statistic directly. I regular attack will do a characters attack level - the defenders armor in damage. A "power attack" will do Attack Level x 1.5 - armor, and so on. It's simple to understand, but not particularly interesting.

You *could* use damage types as imprints. My initial system used a triple armor type of approach, where all units had a value for each of the armor types (and even specific armor bonuses described in their special abilities). Since all damages would be of either type, it was deterministic, but not all units fared the same depending on what they were faced with.

It allowed me to trully build an appropriate infantry/archery/cavalry/pikeman logic in my game where all interactions made sense.

For example, the pikeman would pierce the cavalry's armor easily, but not the infantry's, and the archery would decimate the infantry and pikeman easily, but not the mobile cavalry, etc.

If you can make your system revolve around a small amount of damage types, it can remain straightforward and yet have some depth. Larger stats will still be better (after all, if you have a 13 Slashing damage, even if its the highest armor score of your opponent, I bet you'll be able to dig in some damage anyway).

In the context of an RPG, it would be great to field axemen (slashing), man-at-arms with their hammers (bludgeoning) and lancers (piercing) to insure you have an answer to each enemy's armor. Plus, having actual 'piercing damage' that ignores all armor on weaker attack units would give you versatility at the cost of overall damage score.

These are options the player can enjoy having and gauging.

I've thought about adding a weight stat to all equipment. This would effect a characters initiative and possible movement. Going lightly armored would allow you to get around a battlefield very quickly, but heaven help you if you get caught by something big and strong.

That'd be interesting. Movement against resistance or ability to deal more damage is also an interesting player decision. If you could put it in a concise way, it'd be better:

- Regular armor (armor: 3)

- Better armor (armor: 4, lose 1 movement point)

- Regular Sword (dmg: 6)

- Better Sword (dmg: 7, lose 1 movement point)

The player could technically create a more tanker-variant of the unit, or a more vicious one, or even both, knowing that mobility might become an issue.

Been thinking about how to balance out extra turns that some chars would get over others movement-wise. Balancing damage output seems workable (you do half the damage twice as often kind of thing), but movement is a little more tricky I think. Maybe its just ok to have smaller weaker units running all over the place. Maybe I should just leave it be for now and adjust later if necessary.

This depends on how you plan on using terrain. If your mobile units can easily access the higher ground, and it gives them +20% damage on their ranged attacks, they won't necessarily be weaker even if their weapons are. Before long, they can decimate their enemies while keeping out of range too easily. On the other hand, if terrain is largely unused, or only prevents mobility, then the absence of a strategic advantage will make it not desirable to have mobile units.

You have to strike the right balance to make this viable, and terrain interactions will be key.

I've thought about having multiple attacks (2? 3?) with counterattacks from the defender be the standard. This seems like it has pros and cons. Pro: It allows for a diverse range of modifiers. Example: Burst damage, a character performs all 3 of his attacks immediately and does not recieve counterattacks until the end of combat. Con: It kind of clashes with the initiative based turns, where I am already trying to abstract the effects of speed on combat.

I'd go against that personally. You want players to make decisions. If one decision creates a sequence of 'things', its not as fun, and the strategy depth is lost on the player.

Counterattacks can be interesting, but they shouldn't be the norm. Perhaps there are conditions to be met, or special abilities to have. I can see a pikeman having the 'first strike' when an enemy comes in range (kinda like Overwatch in X-Com for example) but if every unit gets to retaliate when attacked, they don't really need to attack themselves, just make sure they're the painted target.

I'm not convinced about the combination of unit-level turns and two actions per turn. One action only would be conceptually simpler and increase the importance of turn order and speed (e.g. allowing a fast unit to retreat after seeing the enemy advance, instead of letting it act only after the enemy has completed a move+attack turn).

This creates a number of bad corner cases:

You'll play cat and mouse with ranged/melee encounters where the ranged unit seeks to remain out of range until you change your mind, and the melee needs to keep chasing, knowing that, when it stops, its going to receive a pounding.

Giving them the move/attack or move move alternatives allows the ranged unit to do kiting damage, and the melee unit to double move to close on the target. If the ranged unit opts for a move move to move away, then the melee unit can also move move and exit the range of the ranged unit. Also, given the terrain, a well placed move-attack by the melee unit might corner the ranged unit and result in an engagement.

On paper, it doesn't look good, but when you actually start playtesting, it solves a LOT of boring problems that occur on tactical landscapes between units of different class.

You mentioned that units have a set of stats that never change. Is there any type of advancement (automatic RPG-style, new equipment, heart container collection, buying upgrades with gold/credits/cash, etc.)?

Indeed, what is the vector of advancement of the player? Is he present in the battles as a character, or are only his troops depicted?

How do you hire/acquire new units?

So lets take two characters, one with a speed of 9, one with a speed of 5. That translates to initiative scores of 12 and 15 respectively. Character A gets a turn every 12th round (so, rounds 11, 22, 33, 44, etc). While character B gets one every 15th round (15, 30, 45). So in this case, character A would get turns 3 and 4 (33 and 44) before B gets its 3rd (45). It's the initiative score that I am thinking about adding the weight dynamic to.

I think you've made a number of mistakes regarding character A here, correct?

20 - 9 = 11, not 12.

Likewise, its every 11th round, not 12th (numbers in parenthesis would thus work)

Well, terrain is something I would love to do more with, but I feel like I'm not going to just based on all the other things I'd prefer to spend my time on. There will definitely be mobility effects from terrain, and one thing I do absolutely intend to include is skills and spells that modify terrain in some way (though this may end up being the ability to summon and/or place walls on the map).

I have to advise you to make good use of terrain. You may not realize it yet, but a strong part of tactics and keeping the game fresh will come from terrain being different.

Good luck with everything else!

Well it's good that you're thinking in phases then :)

That said, if there is anything such as a Minimum Viable Product for a tactical oriented game, terrain effects definitely needs to be on that list. Direction facing is optional (a lot of good games do well without it) but I've yet to see a very fun tactical game that does not use terrain in any way shape or form that's interesting.

And before you say "chess", remember that the bishops have their own colors ;) One could argue that they are color-bound because of their movement pattern, but from a gameplay standpoint, this makes terrain matter (if my king on white? 'cause his only remaining bishop is white, and if I keep my critical pieces off "white", then that piece's value diminishes greatly).
