Sonic demo on Live now

Although presumably we'll have to wait a little while for the full impact of X06's Live Marketplace offerings to be made apparent, one particular bit-crater over which the dust has settled contains a demo of SEGA's new Sonic the Hedgehog title.

Shown off on both PlayStation 3 and Xbox 360 at the Tokyo Game Show last week, and previewed and everything, the new title sees Sonic and a few of his friends (including the blasted Tails) taking on Sonic Adventure-style levels, which mix insane speed and puzzle-solving.

New characters include Silver the Hedgehog, who can use telekinesis to manipulate things, which is great for solving puzzles/showing off SEGA's newfound love for real-time physics.

I have to try it out.

where we can see the demo?
