20. Tales from the Borderlands
It was fun. Really fun.
I never really did well with Borderlands on its own (beyond co-op anyways, I doubt I'd ever go single player), and I never beat a game, but i love following the series and story (and characters). I DID play Tales from the Borderlands and oh MAN what fun. The loading was pretty shitty and I didn't find Sasha terribly charming (so I was a "minority" who didn't ship her and Rhys :P), but it was a great ride to follow along. I presume it'll be canon to the rest of the world??
