The huge increase of registered players is partly due to www.lolga.com Rocket League being released for the Switch last November. However, I think that the growing population of Rocket League Items  Rocket League fans is because of the game's availability on all major platforms, and most impressively, the ability to cross play between those platforms (with limitations on Sony’s PS4). Developer Psyonix also promised fans that more information will be released soon regarding Season 7, which will probably receive an announcement later this month. 

The game has also been popular with modders for the PC that just last month. YouTuber Jon Sandman released a video showing off a modded map he created that introduced racing in the game. I don’t know about you, but I think Psyonix should include an official racing mode mini game in Rocket League so players can compete in the race tracks as well. You can check out more details on the mod here.
