I might disagree with you there, mate. I think it has an impact on GT7. It looks great, but you smell the stench of crossgen. Just beaten GT7, a great game but I would rather play a more casual racer like The Crew 2. Sim racing to me in closed doors feels a bit outdated to me now, and waiting for The Crew 2 update next July as I like intense body modifications and roaming around and having a variety of modes.
GT7 credit is too easy as well, not sure about those noobs and what are they whining about. Also AI is kinda easy to beat on Hard as well in most modes. I liked the grind for top cars on The Crew, GT7 you can buy a Bugatti after like 1 tournament (the final one), like 30-40min max and still have money to get plenty of other cars.
