It's a beautiful version of Sonic 1. I don't even like Sonic 1 that much (it's cool) but this level of dedication to providing the absolute best version of a single game is something I would love to be more widespread. It would be cool if there were more documentation or something but what you get is a perfect version of Sonic 1 with additional options. Really wish more companies would release respectful versions of their games. I guess these Sega Ages weren't successful since they have discontinued the line, this saddens me.
