Rocket League features many cosmetic items. Players traded actively (exchanged items), and an entire business empire of trading platforms was built around it.
However, it was recently announced that player-to-player item trading in Rocket League will be disabled: this radical policy shift caused a wave of discontent. The game began getting review-bombed on Steam, and its reviews are already mixed.
Entrepreneurs who made a living from Rocket League took a serious blow. People like the creators of the Rocket League Garage platform have effectively been left without jobs.
Developers at Psyonix previously accommodated and helped the creators of trading platforms; such a controversial decision is being attributed directly to Epic Games.
