We knew they were looking to fix the PP bug for a while now, it's no surprise they finally did. There was plenty of time to get to 100mil in the bank and never have to grind again in the game.
That's a great assumption, that everyone has a ton of time to just grind in Gran Turismo. And the "never have to grind again" is an absolute lie. You can't buy all the cars at will, as they have variable availability (invite only, UCD and Legendary cars). Then you have to take into account the tuning costs for each car, which on average, for road cars, must be somewhere around 300k. Add to that, that almost every road car gets parts that can't be reverted back to stock form, without
paying a lot for a new engine (widebody can't be reverted at all), this makes people like me, having to buy 2 of each car, maybe even 3, if I want to make a top speed build without the widebody.
In previews games, you could get a lot more money, faster, and the game didn't have as many super expensive cars in it.
To fix the bug, one would think that they would come up with a proper way to earn Cr. Maybe give players more variety of races that pay well, which is probably unthinkable. It's not just about how much money you get per hour, it's how much fun you can have while grinding. Setting custom races, should give a decent amount of Cr. an hour, even if it's not the ideal amount, like the 3 million or so possible with the glitched Tomahawk, 1 to 2 million an hour, would be decent. Right now, people will still rely on a small number of events to get a decent Cr. flow, which takes away a lot of the fun.
