Classic Gran Turismo game for Vita would never work since you can't drive properly on handheld console for more than few laps.
I would welcome the GT CrossPlay App for Vita where we could get plethora of advanced functionality and benefits from pairing with the *big* GT game.
GTPSP was a game ahead of its time design-wise and despite nobody understood the structure which was perfect for the handheld console, that kind of in-game structure would be the only logical for the handheld, AKA GTVita. So driving part could be solved with the same system of Event Generator as in GTPSP (which would be also be perfect for GT5, still can't understand why don't they just introduce it as some kind of "Cup Racing Events" in the A-Spec mode), but with XP/Cr/Prizes integration with the *big* game through CrossPlay.
But GTVita should really be a accompany to the *big* GT game on normal console where CrossPlay could be used for great amount of possibilities:
- B Spec mode Cross Play
- B Spec mode Online MP (my Bob vs my friends Bobs in the real-time > still can't comprehend the omission of the real-time B-Spec in GT5 online)
- B Spec mode Remote Racing (as it is in GT5)
- Cross Play Car Tuning (Garage)
- Cross Play GT Auto Maintenance & Refresh
- Photo & Replay sharing
- Replay Theatre
- Augumented Reality PhotoMode (to *insert* GT cars into real-life pictures framed with Vita's AU functionality, would be glorious)
- Item Gifting and Trading
- Chat, Messages, E-mail
...and few advanced functionalities:
- Vita as rear-view mirror
- Vita as in-game real-time HUD with touch-screen scrollable information (speed/revs/gear, map with positions of other drivers in race, telemetry and tyre/vehicle monitoring, real-time lap-times and sectors for all players (as in Bspec/Online of GT5)
But having another *normal* GT game just for the sake of having it on console? No, thanx.
