Fallout 2 would have gotten more things right if the locations in the game actually fit the 50's pulp science fiction post-apocalyptic setting from Fallout. The tribals were completely out of place and the placement of the settlements was completely nonsensical, especially with the tribals living just next to a civilized town. That was understandable back in the 1800s wild west, but that was only because the civilized men arrived while the Apache were still running around and scalping the foreheads of the members of other tribes.
On the other hand, Klamath was probably around way before the tribals arrived, and what's funny is that they didn't even arrive as tribals. They were pretty much civilized people when the Vault Dweller lead them into the valley, 'away from civilization'. Funny how 'away' would only be a couple of squares away. Black Isle Studios clearly fucked up on that instance, as well as a lot of other things in the game.
In my personal conception of Fallout 2, the VD would have died after finding the waterchip, killing the master, and slaying the Overseer. He'd have wandered off into the wastes, embroiled himself in further plots (rather than establishing a new home) and mysteriously dissapeared. The player in FO2 would have started as another Vault Dweller, from one of the other unopened vaults, or possibly from Vault City. There would have been no tribals whatsoever, only survivors.
I wonder how the Chosen One managed to start with skills in Science, Speech, Repair (especially pertaining to mechanical repair), Small Guns, Large Guns, Energy Weapons, Gambling, or even Doctor. That makes no sense, for fucks sakes.
