10 Backwards Compatible Xbox 360 Games Microsoft Are Ignoring
10. Red Faction: Guerilla

Despite the Red Faction series going massively downhill with Red Faction: Armageddon, Red Faction: Guerilla remains as one of the best destructive sandboxes in recent years.
A lot of this can be attributed to the fact that the game's destruction engine, Geo-Mod 2.0, allows you to destroy buildings bit by bit. Although the rest of Red Faction: Guerilla may seem a little generic and undercooked, the game is worth playing just for the destructive capabilities alone.
Considering how well received and popular the game was upon launch, it's strange that Microsoft continue to keep it from being backwards compatible. Perhaps it's due to the fact that the franchise itself hasn't seen a new entry in years or because of the legal issues surrounding old THQ games.
Whatever the reason, Microsoft really needs to make one of the best destruction games backwards compatible.
