Re: Plains, Trains, and Automobiles.
Not to get off subject, but:
I really hate accidental good-guy-force-pushing. When I fight I use it (force push) a lot, and while I don't mind beating the crap out of guards and innocent bystanders while I fight whoever's attacking me when I'm evil; I usually play as a good guy, so it gets really annoying. Usually when I'm fighting and civilians (or especially guards and other heroes) I either have to stop using force push or just accept the evil points and the fact that the guards are going to start helping the baddies try to hack me into little pieces, hence signing their own death warrants.
Back on subject:
I don't think the teleportation takes you out of the game's universe. Well, let me rephrase that-- I don't want to be in the game's universe so much that I want to slog through miles of not dangerous, but tedious bad guys just to get to wherever I'm going. Darkwood Bordello, or Avo's temple, or Darkwood Camp are all good examples of places that you occasionally want to go-- not for anything important, but just for the hell of it-- and you don't want to kill a huge amount of time killing miscellaneous weaklings.
Vehicles would help that, but I'd still feel obligated to stop and help the dumbass traders getting stung/hacked/beaten to death by the bad guys-- when I teleport I don't have to deal with my in-game conscience.
