I wanted to ask which platform is most likely to be supported.
EpicStore or RockstarGamesLauncher or later 2020 only Steam.
The RDR2 preload has started and I hate the RockstarGamesLauncher.
But if Epic is not supported, then … we have to wait for Steam Release next year.
Red dead is coming to steam next month December of 2019
This is being / has been discussed in another thread, here: RED DEAD REDEMPTION 2 PC ? is it happening?
It will be released on Rockstar Games in November while also being exclusive to Epic Games for one month in November. It will also come to Steam in December, after the Epic Games exclusivity ends (it will still be available on Epic Games after the exclusive period ends).
Join in the discussion at the thread linked above.
