Blarg: I'd buy both Crusader games from GOG in a heartbeat. I was really blown away by the first one. Great extras in the box -- GOG please try to get some equivalent files!!! -- really really great music, very good FMV with a ridiculously gorgeous gal in it, fantastic explosions, mega-neato robots, cool looking environments, incredibly fun weapons, a story that is genuinely moving in parts, and a very wry look at a corrupt world with aspects echoing our own.
This game really built a cool world to inhabit in which you felt the stakes were high and your character was doing something worthwhile. Plus blowing stuff up, setting evildoers on fire, and doing acrobatic shooting with futuristic weapons, which has got to be among the most fun ways to go out there and make a difference.
