Summary: There are a ton of reviews for this game, so I won't go into depth when you can find more here. I will just give my opinion. Fast, furious, and funny as hell. Borderlands 2 is a fantastic game! It is by far the premiere social FPS/RPG out there. The GotY edition ups the ante with the Expansions(very good!), extra gear(it's poop), New classed(decent), and skins(meh). The first two times through the game, and expansions are excellent.
Summary: Very fun game. It has everything you would want in a coop game. Over the top storytelling, gore, responsive controls, and the ability to customize your character make it a must own. I haven't played any of the DLC, but I'm sure it would only add to the 100+ hours you already get out of this game.
Summary: One of the most fun games on xbox 360, in my opinion. I love first person shooters and diablo, and this combines the two perfectly while adding humor making it, and the first borderlands, some of my favorite games. The action is fast paced and somewhat cartoon-like, but challenging. And despite the bright colors and humor, this is definitely a game for adults with some crude language and adult themes (that are all hilarious).
Summary: Fantastic game. We love playing games that offer split screen two player modes. There surprisingly aren't that many! This one along with the Halo series and Left for Dead are some of the most playable in that mode. The world of this game is enormous and the initial play though of the campaign will provide many many hours of fun. A great sarcastic sense of humor pervades the game and the seemingly endless selection of weaponry keeps things fun.
