That's also debatable really. The main draw of GT Sport, the online racing, is plagued with problems. The penalty thread is one of the longest threads in the GTS forum. They never got the BOP right after this many years. Same with the points system. And every week we still get lots of people getting disconnected from the server. Lots of the top drivers in the 2018/2019 FIA season have left the game in recent times because they're fed up with all these issues that PD refuses to address.Well, I agree it’s not the most innovative series anymore, but the quality is up there. At least in GT Sport it is, not so much in GT5/6.
In terms of graphical quality and not having standard cars, yes GTS is much better than GT5/6.
Innovation wise, I really love Scapes, but not much has changed in terms of the driving experience since GT5P. This is the supposed to be the core of the game, but currently I'm more looking forward to taking photos and listening to the menu music than the racing in GT7.
