5. Replay system appears unchanged in a decade and definitely doesn’t look as good as what Gran Turismo put out.
For FM8 it actually is worse than FM7, in terms of functionality. Now the positional tracker doesn't update live during the replay, it is based on where the cars finish at the end of the race. That means that, unless you recognize the livery on the car you are trying to find, it's pretty annoying to choose the specific car you want to watch because you have to pick based on where it finished, not where it currently sits while viewing the replay.
Also, I can't find a way to use the right stick to look around the car when viewing the replay in chase cam? Many people probably won't notice because they will use the (still not great) cinematic/TV style camera angles, but it's a pretty nice tool for organized racing to review incidents.
Over the years the only real change to the replay system was the replays getting shorter. In the 360 era the replays would last about 45 minutes, during the XB1 era they would only last about 23 minutes, and in FM7 if there was rain they would only last about 10 minutes. Haven't tried to run a long race and save and see how long they last this time.
Today I've had great fun creating custom races for my track toys (Bac Mono, Vühl, etc.) and one of the coolest things is watching both weather and time progression in action, say, start under rain at dawn and finish mid-morning (2x accelerated time) with a clear sky and the racing lane clearly drying out; or start in late afternoon and finish at night, the transitions are seamless!
It's nice to finally be able to enjoy those kinds of cars in an FM title. All of those superlight track toy things in FM7 drove like absolute garbage, but the ones I've tried so far in FM8 are alright. I checked the Lotus 3-Eleven out last night, and while I was using my controller for FM8 and use my wheel for AC, its handling characteristics were a lot like AC with heavy on-throttle understeer.
The time of day stuff is great... While it doesn't actually make the racing better, something just feels much more "epic" about racing into the darkness.
The weather stuff I've had a more mixed bag on... I don't like that we can't choose multiple weather conditions now, or that we can't choose starting conditions for changeable weather. The FM7 system was overly rigid and somewhat predictable, and I was really hoping for more freedom to configure weather in FM8, not less...
