Perhaps this isn't the best time/place for this post, but if I could sit down with Kaz, these would be my Top 3 requests for GT5 based on what we've seen so far...
1. The camera positions need to be fixed. The third-person chase cam needs to go back to how it was in GT1-GT3, and the nose camera needs to actually be on the nose of the car, not on the engine firewall like it currently seems to be.
2. All events (with the exception of endurance races) need to have standing starts. And if the PS3 isn't capable of making that happen, please lower the number of cars from 14-16 down to 8-10 until the performance meets your requirements. Playing catchup is both annoying and unrealistic.
3. You need to find an elegant, convenient way to sell GT5's 1000+ cars. The used car dealerships in GT4 were frustrating and the system you used in GT PSP is utterly terrible! Also, please don't flood the economy with money like you did in GT4. Grinding for cash is a time-honored pursuit in pseudo-sims and if you've forgotten how to properly do it, just copy FM3's payout system.
There are other things I could mention, but these are what I'm most passionate about.
