ATTENTION PC GAMERS (OR ANYBODY INTERESTED IN PC GAMING)
If anybody, like myself, has previously had frustration and impatience with the art of modding so gave up completely, I encourage you to try Vortex - modding made easy.
https://www.nexusmods.com/site/mods/1(FYI modding = modifying a game to improve it whether it be for cheats, better graphics, bug fixes etc).
Vortex automatically picks up on "mod conflicts" (where two mods are incompatible and don't work in games) and sets the mods in the correct loading order.
It's only in Beta stage but so far it's running smoothly for me, no dramas. I am having a blast with Fallout 3, which, without mods, is quite bland and outdated.
Nexus has a list of games with mods available for them.
P.S be careful. Scan files before downloading, etc.
