Like I have been saying, I think Chemical Plant Zone is the level and then it leads into Stardust Speedway Zone for the race.
I am curious if both classic and modern variations will race Metal though? Honestly barely anything for Modern Sonic excites me except the thought of the race with Metal.
Also, can we only post links to the screenshots if possible? I really want to keep up with the discussion, but I do not want to see Chemical Plant Zone or the Sonic Adventure stuff until I get to actually play this game myself.
