I didn't give it an extensive test, but as far as I can tell, there are STILL significant UI issues that hamper the flow of the game.
Primarily - loading and transition times, and the ability to get into the right car with minimal transition.
As it still stands - go into a race; pull up a list of cars that qualify; remember list, go to garage to find appropriate car, failing that, you'll have to go buy one from second hand or premium dealer.
When you've got 3-5 second load times between each screen, and about 5-6 screens to transition between, on top of the sifting through poorly laid out (albeit attractive menu screens), you're wasting 3-5 minutes every time you transition to a new race.
Plus loading up into the first screen; you have to press X to get a cursor up - not that the screen says anything; so if you're used to the loading times as this game conditions you to be; you may be waiting 30 secs to a minute before you realise you need to press X.
It's not a big thing; but it is a clear indicator of how the entire UI stinks to high heaven.
Cmon PD. It's easy - we pick the race; you show us a list of cars from our garage that qualify, if none do, you show us a list of cars that we can buy from dealers that qualify. No transitioning back and forth between multiple screens.
It's a shame because the core game itself is fine; if you try to replicate racing as earnestly as these guys are, it's hard to screw up the core gameplay. But GT5 is a textbook case of screwing up a great core by bolting on a really shoddy interface.
