All Sonic Games in release order, this includes notable fan games / fan remakes, in my order I have placed the fan games next to their originals to give a sense of progression through those eras, also I have grouped together some spinoffs as there isnt enough progression to really bother waiting for, so if you wish for a TRUE release order simply set the built in backloggd order to release date. It does not include ports, unless the port has notable gameplay differences, if one port is slightly superior to another, then I have simply placed that later port in place of the original. Compilations are not included, unless noteworthy experiences.

Again I will clarify this list is more made for an ideal playing experience, rather than a 100% accurate historical record however I have tried to maintain the "progression" of the series in this order.

Games purposely not included:
Lost media Sonic Cafe games (Playable ones included)
Most LCD Games (Just play them when you play mcorigins)
Bigs Big Fishing Adventure 3 (Not on IGDB yet)
Sonic Z-Treme (Not on IGDB Yet)
Sonic 3D Blast (Gens) (Just play the directors cut version then saturn)
Sonic Utopia (2006) (Not on IGDB Yet)
