I played the demo and took a chance on the full game. Best decision ever. Loved the setting, the graphics are top notch, the voice acting and dialog are far more in-depth than I expected. Enjoyable throughout. My (minor) quibble is I'd like to have an ability to change the angle of view so I could see even more of the environments.
I played this game initially when it was released. LOVED IT! In a time when 98% of game creators were jumping on polygons, this game went Voxel. So a round wheel appears round and rolls smoothly. That was one thing I never appreciated with polygons of that period: round wheels were n-sided polygons but the wheel STILL rolled smoothly and not at all what one would expect from the visual presentation. And the soundtrack is quite amazing. Now I can listen without firing up the game. I've kept an old Win ME system just to play this game occasionally so I'm really excited to give GOG's version a go on my Win 7 system. Now perhaps I'll make the old system pure Linux.
