Rocket League

Psyonix's 2015 "soccer with rocket-powered cars" concept was so absurdly brilliant that it built a thriving esports scene and sold over 15 million copies before going free-to-play. Its five-minute matches and infinite skill ceiling made it the most replayable sports game ever designed. It maintains 90% higher daily active users than the average esports title, and its player count is 2.5 times larger than #7 FIFA 23's peak concurrent users.
