XBLA conversion of Daytona is pretty rad. Looks gorgeous with very minimal pop in. Controls feel like the DC version, but slightly smoother. Only the 3 arcade tracks, but it has arranged music (from the Saturn version?), 8 player online, and KARAOKE MODE. Costs $10, and I've spent more than that on the arcade over the years.

I heard it is a port of Sega Racing Classic, but I've never seen that.
