20. It's A Sequel To Supersonic Acrobatic Rocket-Powered Battle-Cars
As much as Rocket League might seem like a totally unique and unprecedented phenomenon, the game was actually developed as a spiritual sequel of-sorts to Psyonix's 2008 PS3 game Supersonic Acrobatic Rocket-Powered Battle-Cars.
The game, basically a proto-Rocket League, received wildly mixed reviews from critics and, partly due to Psyonix's inability to market it to a wider audience, it also tanked commercially despite earning a small cult of fandom.
As a result, the team spent a few years doing contract work for other games - such as Mass Effect 3 and Gears of War - as well as developing their own mobile space combat game, ARC Squadron.
It wasn't until 2013 that development began on what would eventually become Rocket League.
