Argh, now I don't know what to do
Know there's a lot of good racing sims out there but, I usually lean more towards the arcade style w/ some realism throughout. GT4 looks to be killer as does the Logitech® Driving Force™ Pro but, I'd hate to go out and buy a PS2 in Nov just as HALO 2 makes its debut.
On the XBOX side, Sega GT2002 is really fun & Froza looks purdy sweet but as far as arcade racing games go, nothing looks to top the GT series.
Its pretty obvious though, the better
racing games are on consoles.
