Borderlands 2 still playing

I've already done a review of Borderlands 2 I played through as a single character and got to the end with the expectation of popping the disc and slotting in one of two games I've yet to play before slowly returning to a few of my older games such as Kingdoms of Amalur (huh I've done a full review but it's still draft, better look at that sometime) or even the first Borderlands.

I'm still playing Borderlands 2.

No I've not picked up the extra content; I'm also not playing through with my original character at the next challenge level. I've started again with a brand-new character. I'm doing all the same missions as before and yet somehow it's not boring. Being set-up with different weapons, different skill trees and a damn fine story makes this seem a different game. Sure I know what's coming and can anticipate, but with a different character I have to approach these things in a different way.

Annoyingly I now have the urge to experience the game through the eyes of the other characters too.
