Loads of great ideas here!
I'll add on I just posted in the feedback section as well:
Custom A-spec races
Allow players to create their own A-spec challenges with appropriate rewards.
Options should include (at least):
Car choice: Manufacturer, Country, Drivetrain, Weight, Power, Year, Normal/Racecar, Modified/unmodified, PP, Tyres.
Track choice: Track, Weather conditions, Time of day, number of laps, fuel useage, tire wear, time change.
AI Opponents (randomly chosen within set conditions):
-Average range below PP/Weight/Power limitations (0%-5%, 5%-10%, 10%-20%)
-Tyres used by AI
Rewards would be automatically determined based on number of laps and chosen "range" for opponents. A 5 lap race with the most competitive opponent-range should award slightly less than a 5 lap seasonal (to prevent seasonals becoming obsolete). More laps would cause a linear increase in rewards.
Custom races should be saveable and shareable.
