Too short? Damn that's a first Iv'e been playing for a few days and im not even half way done I don't think, im doing everything in no order either, there is a shit load to do. I don't mind the walking something interesting always pops up. Once you uncovered a destination you can fast travel there.
Right now I'm in a Vault and their is hella monster mutants in here, I went through this cave with lil kids in it. There is this Mutant in there that can actually talk and is locked up in a room anybody let that foo out to help you get the G.E.C.K shit? I wanna know if he will betray me if I do.
