Super Mario Bros X

[ThePortalGuru]

And you thought Super Mario Crossover was good

This may just be the best Mario fangame to ever grace this world. Basically, it's a game that combines just about every current Mario game (except Galaxy), every power-up, including Yoshi, and adds split screen co-op, 50 unique levels, and loads of other goodies to play with.

And the thing is, it still feels like a Mario game.

I honestly find the whole concept and execution incredible, and I am downloading the game right now.

You can find the game here, if you're interested.
