Borderlands 2 or Dishonored

Dishonored

B2 - that's for sure.

Dishonored. BL2 is really, really bad.

Watch both Zero Punctuation reviews. Trust neither implicitly, but pay attention to the specific flaws he calls out. Then laugh and disregard his opinion, and go research which one -you- would prefer in a different way.
Because what do we know about what you want out of your money?

Dishonoured.
And do you really want to play a game filled with fugly characters? (Borderlands 2)

Borderland 2 isnt that bad to singleplayer tho... ok its mutch more fun with coop partner, but i have a char for solo as well, and i still enjoy it... I havent played Dishonored, so i cant say that bl2 is better, but it is a great game i can tell

Dishonored for Single Player.

I had a lot more fun with borderlands 2, especially with all the DLC's.
