For those of you who don't know, mods are when you create custom maps, textures, models or other files and use them in a game. Some are just cosmetic, others can drastically alter the game.
Naturally, there are plenty of people who have made Mario-themed mods for PC games. These are some of the ones I've found. If you have the game, I'd say you should download the mods and give them a try.
Doom II A pretty awesome Doom II mod which replaces enemies, textures and such with Mario-themed ones. This one is a lot of fun. You'll need Skulltag or a similar program to run it, though. It'll work with Doom II, Plutonia or TNT original wads.

This mod features Mario as the playable character, although a lot of other mods are also used in the second video. Still, it's pretty damn funny.

Mario Skin, Grand Theft Auto Downloads, Grand Theft Auto Skins Halo This mod is mostly just a bunch of colorful texture changes. Not that impressive, but worth a glance I suppose.
Here's a slightly better one, althought it's just one map.
