UPDATE: I've added several games to the list, bringing the total to *212 entries. Just when I think I've found them all, more obscure Sonic games show up.

I'm playing through EVERY SONIC EVER. I've made it my mission to complete each and every Sonic game ever released. I actually started this little project a good while ago. I've been keeping a detailed journal of my experience with each game, so maybe I'll do something with that later down the line, like a big retrospective video. In any case, it's been an adventure with high highs and low lows. I've only been keeping this list for personal use. It's possible there are some mistakes. It's more or less chronological. I know there are some oddities on the list, so feel free to ask questions. Anyways, just thought I'd share what I've been up to.

SOME NOTES:

----------------------------------------

• Some games are currently lost or unplayable. Mission failed I guess. Eh, I'll just pretend those don't exist.

• Emulation and cheats are to be avoided when reasonably possible.

• For games that technically can't be beaten, all that's required is to play them.

• I've split the games into eras of Sonic, which are mostly arbitrary. Don't take them too seriously.

• The list doesn't include fan games or ROM hacks for now.

• The list only includes ports if they're significantly different or I just feel like including them.

• Some non-Sonic games are included if Sonic characters are prominently featured.

• The list is a living document and continues to change.

• Compilation games generally aren't included, but I do play them when I can.

• The "✔" is for games I've finished so far.
