Forza 3 made the best use of the Buttkicker (bass) than any sim I played so far. One of Forza 3 weak points was it's FFB. This of course means nothing to the majority who uses a controller but for those who only races with a FFB wheel it was a majority let down. Even though there were complaints there was very little rumble in the steering wheel there was a lot with the Buttkicker. It felt more natural to have the rumble coming from the seat instead of the wheel. When another car hits you in the back you can really feel it. So while FFB was little disappointing Buttkicker did make up for some of it.
Of course I doubt there are many who has a Buttkicker so I can see why they were disappointed with very little wheel rumble.
As far as tracks while Forza 3 had many there were some I really dislike. I rather have a few less track with better FFB (feel the bumps in the road) than more with poor FFB. Still I know I'm hardcore racer as most will be using a controller even for GT5. I'm very happy with 20 locations (tracks) as long they are done well.
