Not a bad game, but neither is it a good game.
The gameplay is very much comparable to Unreal 2. Its just a basic straight shooter about a desperate man, Parker who becomes a miner only to be used as slave for a mega company that is totally forgetable. Weapons are okay along with the vehicles that comes with it since this is one of the few games that could be considered ability to use a vehicle. But otherwise, you'll finish this game within a couple hours or so. Storywise, the game appears to copy the movie Total Recall
Sound is very very average and to say the least, comes straight out of a B-rated movie. Music is nothing but a forgetable music and some don't seem to fit the gameplay at all. Voice acting was terrible on comparable level with Far Cry for the PC. Most of voices appear to be people whose don't know their english very good.
Graphically, the game looks okay, but there are other more pretty games out there. It seemed every texture from the PS2 was ported over. On the TV, they can get away with that because the PS2 will put overlay or filters on but the PC because the resolution is sharp, it looked so and so.
Overall, Red Faction is an average that doesn't seem to try anything new. The problem with the game was when it was released, Half Life, Elite Force pretty much made the game outdated. I wouldn't recommend paying more then $10 dollars for this game. If you want Mars game, play Doom 3.
