1.09 will be out presently to deal with that with extreme prejudice, as well as traditional grinding.
The kicker - the $20,000,000 cap will be lifted because Hagerty pricing will demand cars priced well above that.
I seriously wouldn't be surprised at this point, it's incredibly evident that Polyphony, and Kaz himself, are intent on driving any sort of goodwill that they have banked on since 2010 especially, into the ground at a supersonic rate.
It reminds me of the Willys grind in Forza Horizon 5 - it's simply players hyper-streamlining the resources given to them by the developers within the framework of the game they paid money for. In PG's case it couldn't even charitably be called an 'exploit' considering it took advantage of oversights in the system (mainly Car Mastery trees having different perks for each car instead of standardized based on vehicle rarity) and ultimately didn't do much damage in the in game economy considering Forza Horizon's pretty easy to get money in. In this case? Polyphony knows what they are doing and are very clearly doing it to put more money in their coffers by getting weaker willed players to simply give up and buy the MTX's to get the cars and upgrades they want. And those who don't want to give in, have to effectively grind like mad and artificially pump up the player retention numbers in the time department, which makes GT7 look 'better' to Sony shareholders as a result.
So of course people are going to be looking at running scripts and macros, alongside using PC Remote Play, to get the job done. Considering the fact that Polyphony obviously doesn't respect player's time, why the **** should players respect Polyphony's rules in how to play the game when playing the game fairly is obviously pointless once you're out of the Menu walled garden?
...and we have evidence of Kaz trying to nickel and dime players as far back as GT HD, wanting to sell all cars and tracks individually for a total of over $400. He even wanted to sell better AI and damage as an update.
This is legitimately the best thing. Maybe if this was other devs, I'd be very willing to believe that it was pushed onto them by a greedy publisher who believes that they can nickel and dime players and have it not be damaging to the overall brand. But this is GT, a first party title created by a man who has significant cache and sway within the Playstation hierarchy, especially as it's biggest Japanese figurehead. And he's done it twice before. So at what point do we ultimately call a spade a spade, and have the criticism squarely directed at the man at the top of the pyramid for the developer, the one who is part and parcel with the series' legacy he is intent on destroying and making useless?
