Seven amazing creations that players made with famous games

I play video games for fun. Who doesn't?

But there's only so many times you can play through a level on a three-year-old game before it becomes rote button-tapping: the interactive equivalent of bingeing "House" on Netflix. You know exactly how it's going to go.

Enter the world of "mods."

These are free patches fans create to expand the worlds of their favorite video games - sometimes for the better, and sometimes just for the weirder. Mods can soup-up graphics, add in-game content, or change the ways games behave. Some mods function as entirely new games, with the game they modify running invisibly underneath. Others just exist to make you laugh. The only requirement for playing them is owning the original game they're based in.

Collected here are mods that, one way or another, promise to transform your gaming experience. A few are even so good they make buying their underlying games worth it. That is, if you don't have them already.
