Would be fun to work on, but I need to develop something that stands out from the original game. Psyonix or Epic Games likely holds copyrights, trademarks, and possibly patents for Rocket League ⚽🚗💨 But I could use the mechanics for a different type of car game.

have you thought about doing 2D game development?
I have been loving some 2D game recently
Sure! Had a lot of fun working on a Pokémon clone a few years ago. It's open source but not maintained.
