I spent 30+ hours on Driving School, Mission Challenges and Circuit Experiences on launch. There were plenty of new Circuit Experiences added since launch so Id say there is somewhere between 35-40 hours of gameplay just on those. The only thing missing from the previous GTs is the "buy a better exhaust", "get a new turbo", etc. There are dozens (maybe a hundred even?) races to play in singleplayer but I find them boring because the AI kinda suck (they are slow when ahead and suddenly are fast after you overtake them, but mot fast enough to catch you unless you do some shit).
I always think photomode is dumb and boring in other games, but I love Scapes on GT Sport, probably spent 5 hours on that and am always excited when they add new locations.
Online mode really is great, if you can drive respecting others you can have a lot of fun, unlike any other racing game. They were capable of making a race where you start in 8th and ends in 7th super enjoyable.
