I got an old PS2 Genesis compilation recently, I think it's just called the SEGA Genesis Collection. I'm getting to try out a lot of new games, like Gain Ground, which I was honestly surprised was as fun as it is. I also played a bit of Ecco the Dolphin and my low opinion of the game I've had for a while still stands. Like the music though. I realize I could do better as far as Genesis compilations go, but I got this one for free so I'm not complaining.
I also got PS2 Shinobi which I'm very excited to play. In fact I got a ton of (mostly racing) games I'm playing through now, like PS2 Quake 3, which is actually a fine port unlike PS2 Unreal Tournament which I also got.
