All I have to say is it surprised me!
I've never played X-Com nor any of the other UFO series games but this is a blast to play and with the new mods out there like a mission mod that adds more diversity to the default game you can't go wrong. Im sure the price has dropped since this game has been out for awhile now.
If you have some time to install the patches - 1.5 and 1.6 then do so because they fix several bugs in the game. In 1.6 you don't need the game disk in the drive so it would be wise to download and install it before you begin playing.
Lastly, I think this game surprised me because I lost interest in it after about an hour and didn't pick it up again for almost a year. Now I cant put UFO AL down long enough to write this review. Try it or at least the demo and enjoy a different kind of game for once.
