I have been playing this game since the late 1990s and I come and go from it over the years. I am now back in it as I was in 2008, and couldn't be happier. Its basically like a game of chess with basebuilding. A huge part of this game is the music is epic, esp. for the time period. This game usually makes at least a top 25 games list of all time, for those that understand games since their inception in the 70s. Now GOG makes this easy to play, so even better. Even if its full price at like $5, you will get your money's worth. All this said, there is a pretty big learning curve, so definitely start on Beginner if its your first time. A little hint, skip the lasers and go right for PLASMA weapons!!!
