PD should base the Vita version of GT on a different philosophy. The decision to go 60fps in GTPSP was a big wrong turn in my opinion.
What I would like to see in GT Vita:
1. Native resolution, with no AA, a consistent, locked and v-synced 30fps persentation (60 fps is possible but considering GT5/GT6 have never held on to 60 fps, I would rather have consistent 30 instead of 60). PD can use "Sly Cooper :thieves in time" as a reference for this.
2. A huge career (one of the biggest let down of gtpsp was it was an infuriating mega car collection demo with great physics instead of a full priced game) To me it seems with so much of content GT has, it just doesn't utilize them to their maximum potential.
3. No unfinished stuff in the game be it game design elements, tracks or cars (If your car assets have no cockpits, consider releasing them post launch gradually when you have updated them). This hurts the overall package as it causes inconsistency.
4. Newer and better soung engine resulting in better, less muffled engine and exhaust sounds (do I even need to say this).
5. No dynamic time of the day and no weather. I know this sounds stupid but the vita just isn't powerful enough for this. Give me separate Day, Dusk & night versions of tracks with pre-baked lightning and shadows.
6. A 8 racers grid with Al that actually has "Intelligence", that take risk and defend their position. (I personally found gtpsp's AI to be better than GT5). PD can use race driver grid's AI as a reference.
7. An arcade mode where we get to decide what car each AI opponent drives.
8. Better car selection. Yes GT has introduced some underdog car companies and individual vehicles but where's brands like koenigsegg,Ariel, BAC, KIA cars like Mclaren P1, bentley continental supersports, Pagani Zonda F, Toyota's LeMans prototype etc.
9. Opponents that actually bring upgraded cars (like some of the last seasonals of GT5).
10. A photo mode on the scale of at least GT4.
