The Developer of Rocket League: Psyonix, is teaming up with publisher Tencent to bring a free-to-play version of Rocket League to China. The announcement was made during the Tencent UP 2017 Interactive Entertainment press conference. Tencent and Psyonix will be collaborating to bring a "free-to-play version" of Rocket League to China, featuring a select amount of in-game purchasable content.
They have stated that this free-to-play version of the game will feature the same core mechanics that players have come to know and love, but certain changes will be made for the sake of localization to the Chinese market, as well as various in-game items available for purchase. Since this version of Rocket League will indeed be free-to-play, consumers can definitely expect a large amount of rather expensive micro-transactions compared to the original game. Neither Psyonix or Tencent provided substantial details about how different this version of Rocket League will be, nor did they share the specific microtransactions that will be available.
Psyonix announced last week that they have reached 30 million daily players across all platforms, so it's no surprise that they're making this expansion into China. Rocket League is consistently growing in player base, and Psyonix has said that they will potentially be bringing the game to the Nintendo Switch. I think it's safe to say that this is not the last expansion that Psyonix will be making. Rocket League is becoming a universally popular game, and Psyonix is definitely taking all platforms into consideration. While it's not confirmed that it will be coming to the Switch, it's definitely a very good possibility.
