Skyrim gets Steam Workshop... Whose Next?

[Super Sonic Boom]

For those of you up on Steam, Steam Workshop is a collaborative effort by ALL of the Steam Community to submit game related items made by any person. These items can be mods or skins or additional levels whatnot. Team Fortress 2 and Skyrim now have the Steam Workshop (most likely Portal 2 - or it will get it soon)... what games do you want to see next on the list?

Sonic Adventure DX. making mods is stupid easy.

[Supersonic196]

Sonic Generations, there's already been a surge of modders.

[Tanassy]

..Fallout.

[HereAndThere]

..Fallout.

Fallout?
But that game's like...15 years old by now.
Why would it get one? -shot-

Fallout 3 or New Vegas? 'Cause I have a feeling New Vegas: Ultimate Edition might get one.
