Sonic Jam is a great compilation of the mainline Classic Sonic games... well, ok, they didn't put Sonic CD on here, but the games that are on here are solid enough.

These were actually ported to the Saturn, instead of just being emulated, and the porting process is pretty impressive. It's not exactly 1:1, as there are some sound effects that sound a bit different, and after a while, the music will fade out and replay again, but besides that, the Mega Drive games play and sound as they should.

But in addition to that, there's also the Sonic World segment, a place where you can around as Sonic in a 3D environment, and do some missions, and also look up a bunch of concept art, videos, commercials, and just generally appreciate the history of Sonic the Hedgehog from his inception all to way to 1997. It doesn't seem like many years, but when take the spin-offs into account, you realize just how much stuff Sonic had at that time, and he only grew more and more since.

This game is just an overall nice package, not only being a great collection of games in its own right, but the bonus content it offers is the cherry on top!
