Yeah, I made the mistake of playing 2 and all the DLC/headhunter packs first, and then I played 1. I think if I had played them in order, I would have enjoyed the first game more. It was good, but it just wasn't as good as the second.
I went to the Gearbox panel and signing at PAX this year and a lot of the developers said playing the Pre-Sequel does the same thing that 2 did to 1; you just find yourself wishing for the new gameplay. I can see what they mean. The butt-stomping and cryo weapons and freakin lasers were DOPE AS HELL. *_* I got to play as Athena with my buddy as Claptrap and omg. I don't think I'll ever play anything else again (except Tales From the Borderlands, because it's amazeballs. And Inquisition. Okay, that was a wildly inaccurate statement, but srsly, it is SO GOOD Ahhhhhhhh).
ANYWHO! I've only ever drabbled in Borderlands as Maya. I wrote amusing Echonet podcasts as Gaige to send to my buddy on deployment a few months ago, but I've yet to RP in the verse. I'd totally love to write through the main campaign with any of the fellow vault hunters, or write more slice of life things about Sanctuary.
Aaactually, since this is the last RP I'm looking for a while, I think I'm going to set up an interest check just for it. Still totes happy to write with you in Borderlands or HP, of course.
