Same here, I'm sick of the sight of the first two areas of the game after playing it four times already for each of the base characters. It's why I can't be arsed to start TVHM with my main.
If they do release anther character I'd hope there was an option to star at level 35 or something to be honest. After doing a least one play through with all of the existing cast plus TVHM playthroughs with Zero, Slavador and Gaige, I couldn't face having to go through the whole slog again.
I'm always interested in more customization. If it's 400 points, I'm in.
Hoping for another character at some too. Especially if they turn out to be as different from the original cast as Gaige.
All the eurogamers who actually play with each other on xbl rather than just post pseudointellectual pc handwringing bollocks on the forums, love the shit out of biggy.
