Interesting compilation. You get Sonic Cd (US ver), Sonic R, and Sonic the fighters. In addition to that you can unlock all the Sonic game gear games and vectorman 1 and 2. At the time this wa sweat because you got to play Sonic cd and fighters. Sonic R was not great. The presentation is nice. It oozes nostalgia like mega collection but not as good. You could unlock a bunch of secrets and art and music in the gallery by completing missions. Overall it’s ok. Mega collection is better due to better games .
