I played it for 3 days. It was cool.
Except in a game that's main selling point is GLORIOUS GLORIOUS LOOT! :D
I found the drop rate to be ridiculously low. Like 1 gun per 17 enemies. (usually a pistol) Like, I'm not expecting them to explode with loot, but it was disappointing.
Also Gunzerker gets kind of boring after a while.
