This sequel is incredibly unforgiving. First they hold your hand so tightly you're just doing whatever you're told and then without warning they just let you go. I simply got battered with priority missions literally for hours, so much I couldn't even get a breather and just upgrade some weapons and armor or even build facilities. Apart from countries leaving you, XCOM1 was a lot less hardcore and more laid back.
I'm also very annoyed with the breaks between each character's turn. Why the pause of like 4-5 seconds after each fucking miss?
Also, I think it's lame that the enemy always gets a free "getting to cover" turn every time you get within their range. XCOM1 had this too afaik but somehow in that game the enemy didn't butcher your entire squad if you didn't do everything perfectly.
PS: I could swear there's a hidden -10% Aim for the player...
