I know you messaged me on steam, but I'll respond here anyway.
'Fraid I can't split the game with you. Wouldn't mind doing so (although the savings aren't actually all that great on the 2-pack), and while I would be interested I would only do if it I were to be playing with someone.
And I'd play with you, but I'm already like full-time devoted to play Borderlands 2 with another friend, lol, and we're trying to spend our time and finish it before I go to uni and have to try and understand Welsh accents.
First come, first served for my time, sorry. :P
