The halfway point should be just after Bright Lights, Flying City, feels about halfway anyway. --- http://img356.imageshack.us/img356/8325/scrunchface2copyfx0.png http://www.xboxlc.com/cards/default/alle5.jpg
I'm level 17 but feel like I'm rushing through a bit. I just rescued Rolan, am I very far through the main questline?
How big this game is depends on you.
The game is quite lengthy if you decided to do all sidequests on both PT1 and TVHM mode for one class alone on MS than do all 3 DLC. Throw in farming for legendary weapons, playing co-op plus doing the other 5 classes plus at least one more DLC. Hours of entertainment if one chooses.
