I had some ideas regarding Sport Mode!
-First, I had an idea for the Daily Races. They could return to being truly daily, but there could be a algorithm-like way of which races would be on what days. So there'd be some days where the races are repeated annually on that day, and are based on a combination of real-world race & event dates and various anniversaries. Then there could be a listing of races that could be somewhat randomly picked for most of the other days, including races based on FIAGTC World Tour races, or races based on those from various campaigns in the Gran Turismo series. (This would still permit new content to be featured, since some cars/tracks could fit into a pre-existing motif.) I think with all the cars/tracks and other potential rulesets, 365 doesn't seem as big of a number, haha. I wonder if the trophies for poles/wins were easier when the races were really daily?
-Next, I wonder how Pro/Am distinctions could be implemented? I think it could be quite simple: if we use the current system in GTS, any player who's DR A or higher is "Pro," and everything lower is "Am." So if you're in a field of DR A and B drivers, and you're DR B, you can get eligible victories/poles in the context of your class, rather than the entire field. You can also get a bonus for class victories and an even larger victory for winning overall.
-On that note, I think credit/exp payout should be more like the championship points yield, where it's based on the DR of the field, rather that what cars are being driven.
-I also wonder what could be learned from GT Academy and its emphasis on Time Trials? Especially with Sport Mode Time Trials being a recent addition to GTS. Like if some championships could only permit you to enter if you set a time within a certain threshold, like how some real motorsports only allow the slowest eligible time to deviate from the best time by a certain percentage. This would be opposed to building DR in Daily Races to be used in the championships to be matched with a higher-yielding field, whereas I think the Daily Races should have their own ladder, while each championship should have its own respective ladder instead of having one feed into the other.
