Borderlands 2: Game of the year Edition features:
Handsome Jack - if you need a villain, why settle for a growling monster, if you could have a verbose and dapper fellow?
Sweet, sweet loot - procedurally generated guns, shields, and mods of all sorts will have you always searching for something new
Interesting classes - Borderlands 2 gameplay wouldn't have the same vibe without its creative, fun classes to play with
Excellent co-op - why would you go solo? Bring a friend or three and show Handsome Jack where he can put his robots
Sense of humor - being serious is overrated. Dry wit, silly jokes, and situational humor make for much more enjoyable game
Game of the Year edition - nearly all DLC in one place for a fraction of a cost. How can anyone pass that up?
