 A: Many of the options you picked in the installer can be changed at any time. Go to your Fallout 2 directory and look for a file called ddraw.ini. Look through it for any options you wish to modify. "EnableHeroAppearanceMod=", "DamageFormula=" and "NPCAutoLevel=" are some of the options you could have set via the RP installer.

However, I suggest only making changes to this file if you really know what you're doing or were told to make a specific change.
