I've been playing racing games mainly in the form of F1 for ages. Since Formula 1 '97' on the PS1 and more recently the Codemasters F1 games, Forza and Project Cars. (Hated Rallying/Rally cross....so didn't get into Colin McCrae and the likes).
Always used a pad....tried a wheel and pedals set up but it just didn't work for me at the time....although they are more sophisticated these days and might have another crack with a wheel at some point.
There are some fast lads and lasses who use the pad and can drive exceptionally well with them.....but not me! I enjoy the whole driving game experience though. It's just so immersive. The cars, the tracks, the sounds, the racing, the telemetry/stats, the visuals. I love it all.
