Quietly patch and not acknowledge publicly would be my guess
Oh they'll acknowledge it....
" - Various other issues have been addressed."
But yeah, this was in no way intentional and they're probably quite embarrassed.
I hate being cynical all the time but this game
reeks of being design for loot boxes. The original (lower) payouts were still enough to acquire a steady stream of vehicles from brand central and the used car dealership. But 'legendary' cars were priced well outside the range of the standard game economy and the highest level tuning parts / engine swaps were made almost impossibly rare through normal gameplay.
Rare parts and cars would've been made more accessible through the sale of loot box style PSN transactions. Think "special" or high level 7, 8, 9, 10 star tickets with much higher chances of winning rare parts or expensive cars. Sure, you might not win the car you want the first time, but if you could sell that car (for say less than half it's value in game) then your money wouldn't be
completely wasted and you could just buy another special roulette ticket. Rinse and repeat.
Or....
If a particular expensive car pops up in the legendary dealership, you could grind away for the next few days but probably still come up short on credits. But the car is now listed as low stock! You don't want to wait months to see the car again do you? If only there was some way I could top up my credits?
But then the winds started to change (well, in Europe at least). There's a lot of heat being brought at the moment from regulatory bodies in many countries about the exploitive nature of loot boxes. Some games are being outright banned because of the practice and the spotlight on these exploitative practices is only getting brighter. In my opinion, loot box style mtx were pulled from being included with GT7 relatively late in the game's development.
Unfortunately you cant just pull a major design feature that has it's tentacles all though the game design without unbalancing everything else. They were left with a 'broken' game economy where players could not reasonably attain the included content without spending literally thousands of (boring grinding) hours or thousands of dollars.
The players revolted and the game was bombed on social media. In an effort to placate the masses, the game economy was altered to compensate for the legendary priced cars with race payouts being significantly increased. Now the expensive cars are attainable but the regularly priced cars are almost completely devalued. It didn't fix with parts rarity problem either with some regular players still yet to win a single engine swap. So players get thrown an Oprah style bone and "Everybody gets an Engine!". Then somebody at PD forgot to close the door to the engine warehouse and now the shelves are bare.
Now everybody has all the credits, all the cars, all the engines and Sony probably made f-all from the so-called microtransactions (save for the poor buggers that AFK'd their PSN wallet) and to top it all off, despite making an amazing game in many respects, everybody is still dirty on them for pulling this **** in the first place.
Or IDK. Maybe they just made a bad game by accident.
