Every time we try using the Epic Store instead of Steam or GOG, we're always struck by the weird limitations they've built into their systems. Today, when claiming our weekly free games, we found out they added a Collections system to sort your library. So we started going through, setting a collection for each genre, only to realize they have a maximum of ten collections!
Meanwhile, we currently have over thirty designated collections on Steam (pictured here). By no means have we gone through and created comprehensive sorting for our Steam library: we have literally hundreds of games attached to our account, so taking the time to file every one would be a chore. But any time we start a new game, we remember to pop it into one of these boxes. And it allows us to be incredibly granular, since "Platform" and "Platform Action" mean two entirely different things to us.
We could absolutely use that granularity with the Epic Games Store: we've been claiming free games diligently since it first came onto the scene, along with buying a few timed exclusives here and there, which means we're now sorting through hundreds of games there, too. And someone at Epic clearly saw Steam's collection system + realized it could be a big help for their own store! But time and time again, it feels like they're slapping Steam's features into the Epic Games Store without the same level of execution. And as someone who desperately wishes someone would come along and eat into Steam's PC dominance, it's deeply frustrating.
