They didn’t universally slash prize money but they did rebalance it. Prior to the update a number of 1 and 2 lap races paid higher than 5 or 10 lap races. So they reduced the short races and buffed the higher. It does mean a reduction in how much you could earn per hour so while the rebalancing I agree the payouts are still low.
I also agree with Yamauchi about not playing the same race over and over to farm credits. The problem comes that after the cafe books the amount of credits you can earn does reduce. So with the FOMO with the limited offers, or having a £20mill car so early in the games life, it is going to push people towards micro transactions.
On the balance though, the games has been out 2 weeks so I find moaning they can’t buy all the most expensive cars already ridiculous. There should be an element of earning credits and having to think about what cars you buy, especially the exotic and legendary ones.
This is on top of that the numbered GT series have always been about the grind. Buying some second hand shitbox, racing it until you can modify it to do some more races and afford a slightly less shitbox. Rinse and repeat until you can eventually buy a shiny new car.
Forza Horizon is a perfect example of going to far the other way. You get given so many free cars and money that you can get gifted the best cars almost instantly. GT sport also fell in to this somewhat with the gift car for the daily marathon.
There’s also the element that people seem to focus on the game is complete when they finish the cafe books. Ignoring all the additional races the are available at the tracks.
So in summary, the payouts are a little low and there isn’t as many races as I thought there would be. But I think they’re a knock off a point or 2 off the rating rather than the bombing it’s had and overall I’d still recommend the game to anyone that’s a fan of the series.
