I love em. Especially since I bought the Logitech G25 Race Wheel (playing a racer with a pad is a bad as playing an FPS with one, hence why I think many of the above dislike 'realistic'/ non-themed racers). But I'm incredibly picky with racers. I like arcade racers more than simulation i.e. Sega Rally, but they all appear to lean more over to the latter now. GRID was good, but I didn't like this buying cars molarky - why couldn't they have just given me a simple arcade mode ; ;
I'm looking forward to 'Fuel' at the end of this month, so long as I can try a demo first. There aren't enough arcade motorcycle games out there.
Also, I'd love to own Motorstorm: Pacific Rift, and it's my main reason for wanting a PS3 (although if 'Fuel' is that good I may not have to buy it).
Oh, yeah, and the old Wipeout and Rollcage games ruled also.
