You might be interested to know that there are several hardcore modding scenes, where the point is to mod the game for fun. The mod guides are updated every month or so and includes thousands of mods. It takes days to install, and actually playing is optional. In most cases, a new save is required every update, so modders keep an additional playable state if they actually want to play the game.

Lexy's LOTD is my fav one, it's only over a thousand mods, has very detailed instructions, and a very friendly community.
