My impressions as the trailer rolled:
-the advert before the trailer is longer than the trailer
-pegi 3? uh oh...
-oh cool cgi! Sonic running, tails flying... when was the last time we say Tails simply flying?
- a squid? ristar? no, just a yellow squid thing
- color aliens?
- Sonic...
- Colors.
- ah, Sonic Paint?
after reading the press release:
So it's like the storybook games, but now it's a coloring book? Sounds a bit like Mario Galaxy combined with color specific power-ups. Could be cool, could be shit. The whole multi-colored creatures needing Sonic's help on a remote location totally sounds like the plot of 3D Blast.
