I haven't played a Sonic game since Sonic 3, which might be why this one intrigues me so much. And I'm spending a lot of time out of town currently, so the Switch version is the best option for me currently.
Oooh - last sonic game I played was Generations on Steam and it was fantastic.
It was the last sonic game I played from my 2013 Sonic Marathon where I played the following sonic games in a row....
Sonic the hedgehog 1
Sonic the hedgehog 2
Sonic the hedgeho 3 & Knuckles
Sonic the hedgehog 4 Episode 1
Sonic the hedgehog 4 Episode 2
Sonic CD
Sonic 3D Blast
Sonic Spinball
Sonic Adventure DX
Sonic Adventure 2 Battle
Sonic Generations
Bought them part of the 2013 Sonic Mega Pack which had all the games together in a bundle on Amazon for $3.50 total.
