Big fan of GT series and it's the reason I bought the PS4 Pro console (to play GT SPORT)
I understand the microtransaction plan (high chance PD being pressured by SONY) but not OK with the decision to slash the payouts of the best-earning races. Players didn't abuse the game and the races actually do need some skills to win even on the lowest difficulty.
Buying/ fully tune our dream car without grinding is extremely difficult. If linking the car value to the real world prices is important to convey their value and rarity , then the ability to sell our cars for some extra credit will make the game even realistic.
If you compare to many of the game developers nowadays, I would say PD really put a lot of effort in developing GT7. Sometimes, these ridiculous decision are made by those management who have zero knowledge on the community and game but only here to exploit every single cent from the player.
I hope the decision maker can listen to the community and I wish GT7 grow in a way it should be.
