I think Here is my Predictions for 30th Aniversary of Sonic"
A Boost Sonic Game because I want more of the Boost Gameplay
A Sonic Adventure Game that will Bring back the Chao Garden, Station Square and all the Good things that Sonic Adventure 1, Sonic Adventure 2, has
Sonic Mania 2 by Christian Whitehead and the Fan Game Community that might Add Classic Amy Rose and New Levels making a New Experience and a Hub World in that Game
So If Sega Announces the 30th Aniversary Sonic Games, i might think it should be A Boost Sonic Game, Sonic Adventure 3, Sonic Mania 2.
