I decided to try the game out, since it looked fairly interesting.
Haven't gotten very far, but so far the tutorial has managed to annoy me. Why was the very first mission teaching me how to lose all my party members? Why did only one survive? I have a thing for not letting my squad get slaughtered, but the tutorial gives you no choice of the matter. It's a bad way to start a game when the tutorial pisses me off.... hopefully it gets better.
Edit: 6 hours in, the gameplay is fun - though some of the points originally mentioned here are starting to annoy me (the inability to undo your orders like go into overwatch).
But I just hit the first central story mission (Assault on the alien base), and holy f*ck!
It was like hitting a brick wall in terms of difficulty. Playing on normal, I didn't expect to see 3/5 of my squad wiped at the very first fight in the mission. I'm either doing something completely wrong in terms of how I've equipped my soldiers, or in terms of how I play - but as far as I see, unless you have foreknowledge of what will trigger those 4 legged aliens, you can't hope for most of your squad to survive. Thankfully playing without Ironman, so I reloaded... and then probably reloaded like a dozen times to complete that mission. Brick f*cking wall!
Edit 2: After trying my best, I had to relent and lose one soldier on a Very Hard terror mission. This game... I ended up with rescuing 1 civilian out of 6, and losing 1 soldier out of 5. My rating for both those? "Good" ... this game is unforgiving as f*ck. Also starting to hate the RNG. More often than not, my 70%+ shots end up missing. That so far, as a new player, is probably my worst gripe with this game. I've seen shots of a few meters away with a heavy class miss! Even the animation couldn't quite keep up, and showed some of the fired shots connect.. but no - game says they all missed, so I'm effed.
