I got this game and played the first mission and didn't have a clue what was going on. I didn't like how I had to move my people and then figure out which button to press to get my folks to fire. When I bought it I was thinking it was going to have the mechanics like other third person shooters where I could target the aliens and shoot them myself instead of aiming and then pressing some buttons and having the console shoot the weapon. Maybe I should have given it a try, but I took it back to the store and traded it in for Halo 4.
Well.. then you probably had to do more research because it sounds you expected a first person shooter whereas XCOM is a turn based strategy game.
Not the game's fault.
