So I played myself getting Origins?
It didn't even had Sonic Jam's hub world.
Sonic Jam's hub world is a nice nostalgia for me too but it's not something that I played over and over.
For me just the widescreen alone in Sonic Origins makes a huge difference than the other version.
Plus responsive controls, smooth framerate (especially for Sonic CD), secret stage & boss, and having Tails & Knuckles playable in Sonic 1,2,CD (and Amy for Origins Plus).

It'd be solid 10 of 10 for me if not because of this one :

What a letdown.
