I wanted to ask: Are there any particular mods for Fallout 1 ?
I know that for F2 there is Unofficial Patch+Restoration project by Killap but what about the first one ?

There are many mods for FO1, but the game wasn't designed to be modded by players, so there aren't as many as for FO3. NMA would be a good place to start for good quality mods.
