You're right about Fallout, but BG and BG2 can't be done without cracking open the console.
BG1 requires you to go through the story events of the first 4 Chapters to unlock Baldur's Gate, where you can get the last 2 Chapters. Even if you had a dimension door spell available to get into Baldur's Gate early (which would pretty much require cheating, as you can't get them outside of Baldur's Gate or Durlag's Tower) you still would have to do a whole lot of stuff that would take over an hour.
I mean, sure, you could just CLUAConsole Sarevok into existence when the game first started, and then control-Y him for the win, but that's hardly much of a speed run.
BG2...well, just the starting dungeon would likely take a half hour. It's just not possible without cheating/exploiting.
