Napalm Riot

I can't remember the sound being an issue because I rarely played with the game sound on (I usually hopped on a building and blasted everything with the grenade launcher with my own music blasting). The controls were very good, very easy to pick up and learn, and was addicting like an MMORPG because of the upgrades you could do to your guy.

The weapon pack(s?) is sweet too. I suggest getting it if you haven't already, the harpoon gun is full of endless fun.

Fun, replay are obviously high. I beat it probably last year this time and I still pick it up if I'm bored. There's always something to blow up!

Oh, and limpet charges are the best weapon in the game, hands down.
