The overwhelming majority of players are particularly interested in progression, the feeling of evolution within the game, whether in the single-player campaign or even in multiplayer.
I believe the best way to achieve this is by giving players a long history with the car they obtain. Having great difficulty obtaining a car and needing to constantly upgrade and maintain it is essential. Make a new car a major achievement for us, one that requires effort, and give us the option to make various improvements to our car and team, so that we can visually see the difference. We want to look at a car and remember our achievements in the game, not just another car among many options.
A system of individual progression and necessary car upgrades is very important. You can also effectively exploit this by running events to obtain a new car featured in an update.
For example: The new winter update will add the legendary Mclaren F1 GTR, and everyone can get this car for free, as long as they complete the missions to acquire it. And if you want to explore this even further, you can complete multiple missions, each unlocking a part needed to assemble the car. While you're viewing the next challenge, you'll be able to track your progress by watching the car being assembled in the workshop!
Set a time limit to complete these missions and get a new car. For those who don't finish them, you can set a paid option (I don't see a problem with that).
What will motivate many players to never miss out on these free legendary cars is precisely the difficulty/reward combination, as well as the thrill of building your own car.
I'll give you an example of a mission/reward:
Mission 1 - Finish the race in the top 3 with limited fuel (the player will face the challenge of reaching the podium in a race where they'll have to manage their fuel well).
Reward: Mclaren F1 GTR Body
Mission 2 - Finish the timed race in 1:38:200
Reward: Mclaren F1 GTR Suspension
Mission 3 - Finish the race in the top 5 without crashes (A race only with the Mclaren F1 GTR)
Reward: Mclaren F1 GTR Transmission
These are just examples of missions and rewards, with 15 to 20 missions required to obtain the car in our garage, with a limited time limit.
Besides being fun, it can be a new source of income to keep the game financially afloat. For those who can't complete the missions or don't have the time, they can invest real money to complete them.
But don't forget to reward players who complete everything without skipping any steps (for example, a car-themed medal will appear on their in-game profile indicating they've completed all the missions).
Imagine adding specific cars to each new season, motivating players to log in to complete these missions or invest money in the game. If this is a recurring feature, it will keep the game active, with an excellent financial return, and players satisfied with the challenge and reward. But please don't create impossible challenges to try to extort money from players!
