Favorite Sonic Game?

There are lots of Sonic The Hedgehog games, but whats your favorite? Tell me!

I would say Sonic Adventure 2 Battle, i know its a pretty old game, but the ability to raise chao is cool, the levels are really cool, and in 3d, you can chosoe to be evil or a hero, you cna play several characters, and there are epic songs, well, i got to say i really love the game owo

and one off those songs is escape from the city
well its a tei between sonic colors wii and sonic riders zero gravity
sonic colors i liked the many stages and the humor
and sonic riders zero gravity i realy like the extreme gear mechanic

I agree with Chan.

For even older titles, Sonic & Knuckles is cool too. :V

i agree i also like sonic heroes
