Even though it is still possible on marketplaces and websites like Odealo, where you can simply sell your Items on one platform and buy Rocket League Items on another. While it remains the very same game, Rocket League players from one of the platforms are not allowed to trade their Rocket League Items with players that play on one of the different systems. The game excels in its' simplicity, giving players a lot of fun, and pleasing them with eye-candy graphics. Rocket League's popularity has allowed gaming to be published on 6 (!) different platforms, including PC (Microsoft Windows), Playstation 4, Xbox One, OS X, Linux, and Nintendo Switch.

In Rocket League players assign one to four members to each of the two teams in order to start the match. It was developed and published by Psyonix, and first released in July 2015 for Windows and PS4 platforms.
