As I do agree this game is forgeted and got Sonic way out of character, staying with the rings and springs...well... Maybe one or two more Sonic the Hedgehog games like the originals, but after that, they need to think of something new.
But... Sega NEEDS...Let me repeat that... NEEDS to make a Sonic game with lots of levels, possibly new characters, very good looking environments, and... probably one of the best things that Sonic games could have... Chao Gardens. With an 's'. What Sega needs to do is have a big interactive Chao garden, and have all the things that previous gardens had and more. Such as a big pool, waterfall maybe, and possibly a path that leads up to the waterfall and you can go inside a cave behind the waterfall. And it needs those cool items, like the box hat. What would also be cool is some kind of floating objects like a boat.
And after that paragraph of complaining how Sega needs moar chao, One last thing to say.
No single path levels. Is it really that fun to go in the exact direction someone tells you to? Not to me.
