Sonic 06: Well, after rather a lot of pain and suffering, I finally managed to finish Sonic's story. None of it's really good, but there's definitely parts that aren't terrible, and might even be worth some unironic enjoyment. Egg Wyvern, the final boss of the route, is a particular highlight. And somehow, Kingdom Valley even has a Mach Speed section that manages to not be the absolute worst. Crazy, I know, but it's one of those things you can only really understand by playing it personally.
Still gotta get through Shadow and Silver's parts, but I'm definitely not feeling ready to quit by a long shot yet.
