Not The Best but Not Terrible
I heard scathing reviews of this game, but now that I finally have it I'm not nearly as unhappy as the criticism would have it. I really like the original time period and setting which translates into a compelling approach to aliens from the perspective of the cold-war era American heartland. The controls and interface are a lot like Mass Effect but that's not a slight against the game either as they're smooth and responsive. The aliens have interesting appearences and there's a sense of the real origins of X-Com is a way no other game has managed, not even Enemy Unknown I'd argue.
The lowered score is because of hardware issues. The game is fun but it stutters and crashes despite the MacStore saying that the game is playable on the lowest settings. I don't doubt the Macstore so apparently there's some issues, or at least I had some.
