More Borderlands and that's not a bad thing.
Borderlands 2 is a game that gets just about everything right, including the two most important parts of an Action RPG, the Action and the RPG both of which are superb in this game.
Unlike a lot of games where all the guns only serve as a means to kill the enemy, in Borderlands 2 each type of gun is significantly different to the others to give you reason to choose whether to use the pistol or the sniper, this becomes even more varied with the different weapon manufacturers which gives all the weapons in the game their own unique characteristics. The icing on this cake is the elemental damage a lot of weapons offer, which if used right can make an important difference when killing some of the tougher enemies. All of which is supplemented by the fact the actual game engine is on par with any of the dedicated FPS shooters out there including the current king Call of Duty.
As good as all this is though, on it's own it would soon get boring, and that's where the RPG element comes in, not only do you have a variety of locations to explore, and some rather interesting characters to interact with but like any RPG a leveling system not only serves to improve your characters signature special power but also keeps the game challenging. You will find yourself facing tough enemies any time you enter a new area, really making you work for your kills and XP, but later on when you return to these area you will find yourself levels above the enemies allowing you the godlike satisfaction of mowing them down without breaking a sweat. As you continue through the game this up and down roller-coaster continues making sure the game gives you both a pretty decent challenge but also a whole lot of fun.
So to recap, Borderlands 2 is an awesome game... but wait... it gets better.
Unlike a lot of games where the downloadable content adds very little to the game other than to get more of your money into publisher hands, Borderlands 2 actually delivers DLC that is just as good as the main game, giving you reason to either break from the main story or return to the game.
Perhaps the best bit of Borderlands 2, the developers haven't shoe-horned in Multiplayer modes into it, there is no Team Deathmatch or King of the Hill, no flags to capture or bases to hold, just you and up to 3 other people running round Pandora, shooting and looting and occasionally getting your butts handed to you buy some of the games harder bosses.
This for me is the game of 2012.
