I don’t really care about skidmarks because I’m always using the interior view in GT5 so I have a limited view of my surroundings.
In GT4, I did all the endurance races myself the first time. It took me about 4 days to do each of the 24hr races. After I beat them I would go back in b-spec mode just so I could win more money.
I would rather have pitstops where I can decide whether or not to fuel, whether or not to change tires, whether or not to change front and rear tires, or both, and what tire compound to change them to than skid marks.
I’m still perplexed as to why Forza does not include rally events. Maybe they felt they would be copying GT…
Also the longest race in Forza 3 is only like an hour and a half. I hardly call that an “endurance” race.
