With the official statement from Psyonix stating that the acquisition won't change its premiere competitive title Rocket League in the short term. Adding that yes this means the game will be coming to the Epic Games Store but also that it's a great move for Rocket League Esports.
In the short term, nothing will change at all! We’re still committed to providing Rocket League with frequent updates that have new features, new content, and new ways to play the game for as long as you’ll have us.
In the long-term, we expect to bring Rocket League to the Epic Games store and to leverage our new relationship to grow the game in ways we couldn’t do on our own before. We believe that bringing Rocket League to new audiences with more support is a win for everybody.
We think this is a great move for the Rocket League Esports ecosystem because it significantly increases our potential reach and resources, just like it does for the game itself. We really do believe that you'll find our future in esports to be very exciting -- especially in the near future, where on June 21-23 at the Prudential Center in Newark, New Jersey, the Rocket League Championship Series (RLCS) finals will end our 7th season with a bang!
As per the announcement Rocket League will remain on Steam, with the deal itself to be finalised in the coming weeks. Will this mean a move away from Steam in the future? Hard to say, but it's a definite possibility. Either way with the backing of Epic Games no doubt Rocket League support will continue for quite a while - as it joins Fortnite as two of the biggest competitive titles out there supporting cross-platform play across PC, PS4, Xbox One, and Nintendo Switch.
Thanks to AusGamers member The GuVna for bringing this to our attention, including word that since the announcement earlier today recent user reviews on Steam have changed from "Very Positive" to "Mixed".
