Rev Up Those Sonic Cycles

[Baegal]

while the art for the games is great, I am still VERY dissapointed with the list. Almost every single level is a city place.

What happened to places like hydrocity zone(even though it has the word "city", it's 10 times better than any other one),
Lava Reef zone, Sandopolis zone, Labyrinth zone, carnival night zone, angel island zone, and all of the other really cool, different levels?

Everything now is all city levels, which to me, really aren't all that interesting. Why can't SEGA go back to making a larger variety of levels?
