You see? It's all about
compromises:
-60 fps
-tire flex
-16 cars for every race
-extensive visual and mechanical damage
but
-no weather changes and wet driving conditions simulated (based on factors like temperature, pressure and humidity, all in real time) which affect the appearance of the track and how cars handle on it
-no time transitions
-no races on snow/gravel/dirt(Horizon is an exception), with specific tires to choose.
-visually speaking, add body/tires collecting grass/dust/snow and smoke dispersion (in Forza all I see are little clouds)
Also combine weather and time transitions on the same race: it's
A LOT of work. Those are important factors in a simulator, and in real life of course.
I like forza, I played FM3 and 4 religiously, offline and online, but fanboys must stop praising it like it's always superior. The Holy Grail. It's not.
Compromises. It's the same story for all games on console. There are time and hardware limitations.
EDIT:
GT6 is 1440 x 1080 with weather and night racing... on a PS3 with some dips. Turn 10 has no excuses.
This.
With all the power the xbone has, I can't believe they still didn't add what Polyphony achieved 3-4 years ago on an old gen console.
Instead of adding stuff, they removed.
Rush everything to sell a Day 1 game: Must.Get.Monnnneeeey.
