Some ideas from my (big) head.
CITY
A large city, more complete than "Bay" (something like 20 times more blocks). Large skyscrapers, streets ... A vast environment. I figured something like Times Square at night. Imagine a race of TrackMania in a place like this:

UNKNOWN PLANET
On a planet far away, the sky overlooking the galaxy, futuristic cars very powerful, low-gravity... The planet could be a mixture of Mars, Titan (moon of Saturn) and something from Star Wars.
ANOTHER FREE TRACKMANIA
TrackMania Nations (ESWC and Forever) and the demos were important to make the series famous. Another free version, TrackMania is now growing, will launch it in a much higher level, something that even today many games have failed.
I'm waiting for more news about Storm, Valley and QuestMania.
