I'm simply a noob who is very new to the modding scene, and in going from adding Oblivion mods to Fallout 3 mods wanted to know what the "Archiveinvalidation" stuff people mention is all about (something unique to fallout 3 I'm guessing). Also, has someone created a streamlined mod manager compatible with mods for Fallout 3 or was that less feasible with this particular game?
