I don't play racing games, myself. Personaly, I don't see that appeal, as I can go out and drive in a circle right now, if I wanted. And don't say 'it's not a circle.' You start at point A, and end at point A, that's a circle to me. :-D And by the way, author, you didn't put an 'a different game' option on the poll...
...but seriously, if racing is your thing, fine, I have neither the will, nor the power to deny you of that. But nothing really needs 'defending.' Play what you want, and I play what I want. That's all there is too it. Personal opinions are why there is so much variation in everything, including gaming.
