If the list on PCGamingWiki is up to date, there aren’t many Epic exclusives anymore (only 26 currently): pcgamingwiki.com/…/List_of_games_exclusive_to_Epi…

And, earlier this year, Tim Sweeney said that many of exclusivity deals weren’t a good investment while the free games have been “magical.”

So, it seems like a problem that is solving itself over time. Epic will probably still have exclusives going forward, but I would expect them to target a few high-value exclusives like they got with Alan Wake 2. Or, maybe they will just do more acquisitions of games to self-publish, like they did with Rocket League and Fall Guys.
