I love this game, so many small improvements from the first game, and the story follows up really good. You meet a lot of the good old Borderlands characters again, and the game is still hilarious!
Love the new system where you automatically pick up money and ammo when you walk or drive over it. Looove being able to change skin and head of your character and find new skins even for the cars. The game also have so many references to countless movies and games and what not, just take the little minecraft easteregg with blocks you have to melee and actual creepers!!!
Most of all I love the scene of humor they use in this game, from introductions of characters to when you killing an enemy and he is screaming out and stuff like that. Just make this game really enjoyable.
I must say I think it is on my top 3 list of games, between Fallout 3 and Assassins Creed 2:)
