Boosting GT League events seems a relatively low resource way of increasing content for existing (and new) users. Give out some decent Credit & XP bonuses and it can replace the grinding many already do.I’m personally fine with the current endurances being about an hour, especially since there isn’t any dynamic time/weather. I’d wait for the next game to feature that. I’d also make the endurances as long as they were in GT3, as a compromise. Especially since in real life, one driver doesn’t drive the whole 24h.
Also, do the LH Time Trials offer notable experience in addition to the credits?
As for Hamilton.......maybe he can set some times of the newer tracks for his DLC.
