Top down racers were and still are auwsome, I think South Park Chefs Luv shack has a mini game along with Jetforce Gemini. It was a differnt time back then, you know the kinda time when you saw an arcade outside a corner store and said, okay I got an hour to spare.
I don't know anything about current racers, asides for that one racer based off a Comic
( GTO ) for the PSP, Midnight club for the PSX, and tracks for Windows ( tracks is a free online racers, where you can race people from around the world ), the same with flight simulator I think.
I think the last racer I looked at was XGR for the GCN/X-box was it online for the X-box? Then of course Kalleria.

I think I was referencing racers that use that 3d trick, for the PCE, and so forth, Those are also cool no matter what system.
