The thing is that the most of the events in the game are events with low credit rewards, but there are only very few cars in the game that are very cheap like it was in GT4, GT5 or GT6, average or below average street cars which were easy affordable like in real life and gave that the game higher replayability and variability. A certain form of fun and discovering many unknown brands and cars, that thing which has sadly disappeared since GTS.
I still feel that used cars dealership is useless here and it doesn't work as well as in the previous games.
Most of the prices for the cars range from 350,000-500,000/ these are mostly racing GT cars that everyone in the world knows very well. What really dominates are legendary cars/VGT cars that are about 1,000,000 or much, much more. But there are still not enough high paying events for these classes. Coincidence?
GT7 wants to be too serious and professional, I do not know why, but the more and more they try, the more it gets boring and predictable, while the previous games came to me like endless walks through museums with cars. The fun factor is definetly missing here.
