I've heard good things about Heroes even though i've never played it, and i like how there are 3 characters at once that you can control. E-123 Omega is a real favorite of mine, i love his dialogue, although all of the teams have great chemistry with each other. Even though they had to resurrect a certain character because they liked him that much (that's major spoilers for SA2 so i won't go into detail about who it is)
What? You haven't played Mania yet? GO PLAY MANIA! It's incredible! Just make sure you get Sonic Mania Plus, since it includes the extra stuff added later on. It brings back everything that made the Genesis titles amazing. A real downside is that most of the Zones are returning from 1, 2, CD and 3K. There are only, like, 4 new Zones, but they're all pretty good. Except for the last area. That one sucks.
