trade in should be between 16 and 20, and with 110%, that's not too bad for 2 week rental.
also they said season pass is 30, and i will want to get it, or 10 each. but you know in a year they will have disk goty, plus a sale on dlc. but idk. should be a great game.
+ you get the preorder stuff like the mechromancer and vault hunter pack. so then you could even buy used down the line for cheap and get dlc 1/2 off or whatev.
i keep contemplating trading skyrim in cuz i think they will release all the dlc at once for ps3 with goty, and tiv will drop from 33 to whatever low. idk tho.
