I have a lot of nostalgia for the classic games, and I still have a place in my heart for Sonic 1... but I'd be dishonest if I didn't say this game isn't as great as some may remember it. The pacing is all over the place with these levels, and I speak as someone who mildly enjoys Marble Zone... but absolutely can't stand Labyrinth Zone, and also not the biggest fan of certain level design choices in Starlight Zone and Scrap Brain, though I recognize this is an early 90's platformer.

It's a very important game that has its place in history, but Sonic 2 and 3&K - and dare I say even CD - are much more worth your time and funner in general. But go back to it if you really wish to see where this series started, as it still has its value of course.
