Great collection all things considered, but the slow down on Sonic 2 is unforgiveable. Otherwise, basically the best way to play the other games but ymmv on the music (personally I prefer the Genesis originals for all but they're still great arrangements). Doesn’t need a mention since it’s the thing people always point out, but that 3D overworld menu is charming as all hell.

Also no Sonic CD with being able to choose the JPN / PAL / USA OSTs? Sure that's a complaint in hindsight, but c'mon.
