Game description:
Soccer meets racing once again in our long-awaited, MP-focused sequel to Supersonic Acrobatic Rocket-Powered Battle-Cars! A futuristic Sports-Action game, Rocket League, equips players with booster-rigged vehicles that can be crashed into balls for incredible goals or epic saves across multiple, highly-detailed arenas. Using an advanced physics system to simulate realistic interactions, Rocket League relies on mass and momentum to give players a complete sense of intuitive control in this unbelievable, high-octane re-imagining of association football.
Top game. There is a good amount of people playing it on the switch (you can tell because their profile icons will show up while PC/XB won't), but I just play with cross play enabled. The game runs fine and I've played many hours docked and handheld - Two players using a joycon each is impossibly tricky though which is a shame.
