You can have and say whatever opinion you want, whether it's popular or not,
but you can't really expect to get away with just saying "it sucks" or "it
rules", you have to say "I think it sucks because..." ;-)
Some sims really do suck, but in the case of F12002/GTR I don't think it
does, and as you've seen many others think it's great too. As Dave pointed
out though, it has it's failings, and I believe the jury is still out on the
sound distortion. I think it adds something to the experience, and while
it's not the sound you might hear if you were sat in the real car, to my
ears it sounds close to what the mic on the in-car cameras pick up, which is
as close as most of us will ever come to hearing a race spec Diablo or 360
at full chat.
Don't sulk just because other people disagree, everyone has different
tastes. But you have to back up your opinions with some justification,
particularly if you are commenting on such a popular sim as the GTR mod ;-)
