Motorstorm > Trackmania
Could be...but I haven' t played Motorstorm, and you can' t make your own tracks on that either!
But yea, there' s no demo for TM-United yet. But consider the combination of these previous demos...

http://www.gamershell.com/download_11401.shtml - TM Sunrise Extreme
...one big demo for United (hence the term!). Like I said the idea' s the same, it' s just all put together into one big game for this one, with a few tweaks to the online system etc.
Each player has their own myspace like page with all the content they' ve created up for grabs, for in-game currency earned through completing races, sharing content etc.
But these old demos dont allow you to
save any content until you buy the game, only play about with the editors. Like I said though, a lot of people were just happy racing other peoples content and never bought the game, which is why their strategy is different this time...
I' m preloading the retail version myself.
