Check out the track creator for TrackMania for the Wii.

Debuting in Season 9, all players can try a beta of The Crew Motorfest’s new ambitious track creator, TrackForge.

The arrival of Trackmania on consoles and cloud platform brings all the community together
I don't neccessarily love the subscription model (even tho it's pretty cheap) but the game itself is a blast.
well i guess i dont need to get ModNataion racers anymore
this looks awesome but i wish it was on 360/ps3 and not the wii.
