I've been playing Sega Extreme Sports a lot recently and I realised that a major part of it's appeal is the Ninja Tunes soundtrack. It's so well matched to the action, it's almost hypnotic. I found myself sticking the game onto replay and just chilling out to the beats lol

I suppose Shenmue and D2 would be my other choices with Tony Hawks Pro Skate 2 and Matt Hoffmans BMX getting honourable mentions.
