No, this isn't a thread about the moderators (They're doing a good job:ninja:).
I've been playing Fallout 3 for a while now and am interested in mods of the game. Problem is, I have no experience whatsoever of modding.
And so I have plenty of questions;
Will it completely alter my game forever, or are they easily removable?
Any client/s I need to install?
Good places to get mods?
As I'm a complete novice, some advice and/or additional info would be appreciated!
