THQ's Red Faction: Guerrilla (available on the Xbox 360 and PlayStation 3 in 2009) is one of the best and worst types of games. On one hand, it's a sweet third person, action adventure in which you lead a band of miners (on Mars, no less) against an oppressive regime, pulverizing the environments and enemies using any means necessary. On the other, its impressive level of destruction will ruin future games that aren't nearly as accessible.
An excellent physics system enhances the experience, as buildings fall depending on weight distribution, while vehicles sail through the air and smash through windows. Then there's the walker, this crude looking mining vehicle (it looks like a mech) that lets you walk through things or pound them with your robotic fists. Just watch out for falling debris, as it and shrapnel can kill you.
