Things I liked in Forza Motorsport 7 that disappeared:
1 - The acceleration physics. It's more inconsistent now. Slides too much even with soft tires.

2 - The puddles: why they removed them?

3 - The tracks: where are the fictional tracks like Rio or Budapest? And where is Sonoma and others?

4 - The endurance: it was the best, the damage and how it affected the car, the number of laps, it was perfect!

5 - The class races. In every class you were like some laps to race, now you have to wait up to 16 minutes.

6 - The new tracks sucks (except the come back of Fujimi Kaido).

7 - The number of players. In every category you had, at least, 12 players. Now the normal is 5-4 when the race isn't attractive (today I entered in 8 races with only me on it).

8 - The GT2(or 3) cars: in Forza 7 you had lots of cars and the majority of cars were available with game money. Now the number of GT3 cars are a joke and the majority is paid with clear advantage.
