I guess I did too many side quests but I take out everything I see, open every box and chest, sell every item I can, occasionally dropping a couple things in favor of stuff that sells for higher.. anyway I'm level 50, capped xp and I'm not even done the 2nd playthrough.
I hit 9,999,999 and then some, but it seems to still track your money. I bought something for 2.5M and still had 9,999,999 but then I later bought something else and it actually went below. I had thought I glitched the money somehow.
so what now? I'm gonna hoping for some more-badass weapons as well as capping my favorite weapons to 50 (I still can't believe they go that high, I regret using 3 weapon types for so long)
I haven't done the multiplayer, if anyone wants a multiplayer perma I'll gladly start again with a different class, I only have my Siren (which I love love love)
