Sonic 1 - Sonic & Knuckles are gems. Everything about those games is pure fun all of the time. Sonic Adventure was the first Sonic game that had boring sections in it. Before that, I never had a concept of a Sonic game being boring at any time. When I came across the exploration stages and that hub town in Sonic Adventure, it was a total turn off and a game ruiner for me. I stopped playing it because it was destroying everything that I knew Sonic to be.
