8. Worms Armageddon (PC)
For those not familiar, this is a strategy game that involves setting up worms on a destructible terrain and trying to eliminate the opposing teams with various high powered weapons. My friend and I used to play this for hours on end and I just bought it again on Steam and it's my most played game. Banana bombs are probably the most unpredictably destructive force I've ever encountered in a video game.
