How is XCOM? It looks like a lot of fun.
If you like rogue games with a turn based tactic combat like Company of Heroes, this game will be something up your alley. Some of the missions do get rather repetitive, but it's offset by the constant fear of losing valuable members of your team. Last time I played, there were some frustrating bugs from FoV and cover that would randomly let your squad mate lose all defensive benefits or something. Aliens would also pop out of Fog of War in the middle of an advancing squad...
But it's damn addicting. Every upgrade feels so rewarding because of the possibility of losing it. I just wished there was more randomness in the 'choose your poison' missions. It just felt a bit stale that there would be 3 missions to choose every time there was a possibility of a non story-line fight. Oh and I wished there was more components to upgrading the homebase.
But overall very fun game. I got it at nearly full price and have no regrets.
