I haven't gotten a single idea until today lol.
SPECIAL EVENTS
Play this new game mode and get new cars!
Play stages and get blueprints and performance parts. You can't use your own performance parts, so that means you will have to get provided performance parts. On all the stages you will have to use the SE car (for example, Ferrari SF90 Stradale). On the final stage, you will face the discipline king (for example, Tio if the car is from the Street Racing family). If you don't get the car, you will lose the provided performance parts, but don't be discouraged, as the car may be on limited sale for 1 week! If you get the car, congrats! You will also get the provided performance parts and a exclusive decal (only for the people who got it during it's SE)
TRADE SYSTEM
Trade your performance parts with other players!
Don't need some performance parts? You can trade those with other players to help them progress! When someone wants to trade with you, you'll get a notification. You can accept or deny the trade. If you accept, you'll get a screen where it shows what the other player will trade and what you'll trade. After you finished, select if you accept or reject the other players trade. If both of the players accepted, then the trade will finish and you will get the performance parts from the other player.
CUSTOM PERFORMANCE KITS
Order your performance parts on a category system!
You can select which PERFORMANCE parts you want to bring to the category. In order to find those easier to find, you will be able to put a name to the category. For example, if you made a performance kit with nitro alchemist, you can call it "Nitro". If you want to apply those to a car, select "Apply", select the car and here you go!
What do you think about those 3 ideas?
