Fallout – What use does Pre-war Money have in Fallout 3

That's exactly the situation I was in. Yes, you can use Fallout 3 savegames (boxed) with Fallout 3 GOTY (steam) (if you had any mods installed in your original install, it will tell you "Some features of this savegame are no longer available. These features will be disabled." - my savegames still worked perfectly though)

I had to move the save files to a slightly different location, though. My original saves were stored in

C:\Users\BlueRaja\Documents\My Games\Fallout3\Saves\

^{(The XP-equivalent of that would be C:\Documents and Settings\BlueRaja\My Documents\My Games\Fallout3\Saves\)}

My new saves were stored in (and thus my old saves had to be moved to):

C:\Users\BlueRaja\Documents\My Games\Fallout3\Saves\BlueRaja\

I would recommend installing and starting the new copy and, if it doesn't recognize your old saves, create a new game and save it real quick to let it create the save-directory, then move your save files to the new directory.

It's the system in which you can pause the action a take aim at specific body parts, with known percentage of hitting them, and with each action costing a specific amount of "action points" (AP).

It stands for "Vault-Tec Assisted Targeting system", but mostly it

• Gives a more cinematic feel when using it, due to the slow-motion action sequence after choosing a target.
• Makes the game closer to earlier, turn-based Fallout games in which you could target specific body parts with known percentages, paying with action points, in a very similar way.
• Gives the game a more RPG-ish, tactical feel than a typical shooter.
• Makes the game easier / less stressful.

You can read more about it on Wikia's Fallout, Gamespy and even Wikipedia.
