Achievements in Xbox are a huge thing, that's why users have been complaining about EA not having Xbox achievements if you play their games through PC Game Pass. (source: Ea Play games in the Xbox Gamepass (PC) should give players Xbox Achievements - Answer HQ)
So will this be the same case with Extraction? Will R6E have Xbox Achievements if you play it through the Xbox PC Game Pass?
Will the game be downloadable directly through the PC Xbox App or users will be forced to install a whole launcher (Ubiconn) just for a single game? Yes, EA forces users to install their EA Launcher, but they do it because they have lots of games in PC Game Pass. I don't think people will install Ubiconn just to play a single game. That's why I think the game has to be "Play Anywhere" in Xbox, meaning that it's published directly in the Microsoft Xbox Store and users aren't forced to install anything extra, they just play directly from the Xbox App. This also enables Xbox regional prices for countries where Ubiconn Store is not supported. (is just missing the PC tag: Tom Clancy’s Rainbow Six Extraction | Xbox)
Thanks for your time.
