As for the games that were Epic exclusive for a year: Borderlands 3, Satisfactory, Darksiders 3, Hitman 3, Dead Island 2, Borderlands TTW to name a few. They have a year exclusivity deal with Epic - we know how annoying exclusivity deals are on consoles.
About the features, it’s quite tricky. Epic rather spends thousands on exclusivity deals rather than invest into a launcher to have a working basket.
It’s super obvious where Epic’s priorities are, and it’s not the gamers. How are they able to dedicate so much work on Unreal, but now on a launcher? They try to substitute a half-assed launcher with exclusivity deals, because they know nobody would use it willingly.
