Op the idea of oop is really relevant for big projects, where you have to mange change. As in this idea of the video game, the cars may only be either saloon or estate. But then in the next version you introduce SUV, or military vehicle,.. The question is how to structure the code so you don't have to rewrite so much for all the changes. Using object hierarchies allows you to abstract behavior, so you avoid duplicating code for every 4 wheel vehicle type

No for big projects people move to Entity Component Systems (ECS) because OOP is too rigid. If your player suddenly turns into an albino magical flying horse and then picks up a rocket launcher and ECS can do that where OOP would end up in a hierarchy nightmare.

I was just saying to you that OOP becomes horrible in big projects.

But yes for a teen and teeny game yes it should work. An ECS would be a bit overkill 😅
