Why?! WHY WHY WHY is it the only good way to show an experianced hero is levels! Shouldn't better armor/pets/weapons/** and higher skill points do that already! I need your opinion on this one, I see no reason to use levels, but if you can convince me!
How smart should NPCs(friendly) be? Smart enough to run when monsters are coming? does that defy the point? They shouldn't have a negative IQ like in every game ever!
(non friendly) All depends on what they are I guess, civilized creatures should not have a negative IQ euther, bears/etc can though.
Honestly, would you spend time in a single player RPG mining ore and making armor? Maybe if you were a hardcore gamer, is this an important enough issue to require attention?
Which would you like to see more of in a world, grassy plains, forests, barren deserts, scorched earth, snowy mountaintops? There has to be some of each, but I assume players would rather see more nice looking scenes than scorched earth and dusty barren deserts, again I need your opinion!
Should there be holidays in game? They celebrated Christ's birthday in medevil times, and they had the day of the dead, not sure about any more. I could also make up holidays to go along with the lore...
Quests/Events that only hapen on certain holidays? Items only available on such days?
