Yeah bro, all the magic about this game is on the Atmosphere :)
Oh I really never heard about TTW, I need to check for that mod or game, but yeah, most of the mods are only available for Fnv ON Fo4 but, I feel and think that the mods for FO3 have more soul or magic I don't really know how to tell it :D
Cool bro, keep your work.
Regards.
