GN0S1S  On a Mac, the gameplay is smooth. I lost many years of my life to the 3 X-Com games back when I was a PC user (and young). This game does do justice to those wonderful games, kudos to the developers. There are some things to look out for, however...

- Multiplayer doesn't seem to find servers on the internet

- Some text (English) for the game is just filled with the phrase "TODO" meaning they haven't gotten to it yet. This includes the first two man-made fighters based on Alien Tech, and a mid-game scrolling text to further the story along.

- There are bugs, like the imagery of your soldiers in fighting mode don't reflect the soldier currently selected.

I also don't know if it is me, but the Standard mode feels too easy. I find myself building bases just to waste all of the loads of cash I am given, and there is very little alien fighting. I am a huge veteran of the games, I worshipped them and was an expert, so maybe I am biased, but who knows.

This UFO:AI game, in spite of the above, has consumed me again. I'm older now, and it brought back good memories and an old addiction. It is a version 2.2, which means it has a LOT of stability and great development. The graphics are good, and so is the AI.
