It had four DLC campaigns as well, although one was just Moxxi's arena battles that didn't give you any experience. Boy was that a dumb idea. In Borderlands 2, I beat the first playthrough with Zero. I made it partway through THVM with him. I did the first two DLCs in THVM with him. The third DLC I am working through with Gaige after getting her to just before the end of the first playthrough. I haven't touched the other three characters and Zero is only level 46; I haven't even hit the level cap yet. And my playtime across those two characters is about 90 hours. It's already a big game.
