Red Faction was a very unique game when it came out in 2001. Its gimmick was the ability to blast a hole through any wall with its "GeoMod" system. In practice, the mechanic is underutilized in the game. The plot is paper thin, and as a shooter, it's showing its age. But the level design is varied and reminds me of Half-Life (which would come out seven years later). It also has vehicles, which, while novel, are one of the worst parts of the gameplay.
