Simple question, Is the Fallout 3 .esm file like the Holy Grail? In other words, is it the one you never touch or Uncheck when you're in your FO3 Launcher/ Data folder?

What does it do, in laymens terms? :wave:

That's the gameworld right there: the capital wasteland, the quests, the objects, the critters, the NPCs, etc.

Feel free to untick it, but don't expect the game to load after it. It, effectively, IS fallout 3. Every item, every effect, every weapon, everything.

Great....thanks for the help....now I know what that darn file stands for------------------>the whole darn game...lol. Best not uncheck it.
