The fight with Metal Sonic needs to be several battles before Metal Sonic is defeated, not just one fight or one race. He is an epic villian after all. How about Metal Sonic appearing at the end of Acts 1 and 2 of each zone. Like a mid zone boss in S3&K.That will keep Sonic and Tails on their toes.
On average: Sonic 1 had 19 acts (six proper zones). Sonic 2 had 20 acts (eight proper zones). S3&K had 25 acts (11 proper zones). when I say proper I mean zones with more than 1 act. Sonic 4 Ep1 has 13 acts and 4 zones. That game needed at at least six zones. Only having 4 zones in Ep2 would work if the levels were significantly larger.
