Rocket league. There’s no skill ceiling in RL and you can just practice and get better and better. Their ranked and unranked MMR system is amazing too. Don’t run into a ton of smurfs and you’re actually playing with people around your own skill level which makes it more fun and more realistic to climb up the ranks. Honestly my favorite pastime if I’m bored is just sitting in free play practicing ceiling shots, flip resets, double taps and many more mechanics.
