I like having a huge library of games on epic-store but when I try to buy a game there - because they're having a sale - its a pain to find games. Steam's search isn't top-notch either, but its 1000x better than epic's.
For example. I search for "roguelike" and it brings up 1 single game (which is coming soon). There are few tags on games. No way to refine a search. In fact they have a category called "rogue-like" which has a lot of games, but somehow the search just misses them. There's no way to refine results by popularity or most sales.
I suspect this is all an intentional design philosophy of epic, a way to have a lot more control over what the user sees than steam, because its so bad it doesn't make any other sense.
Also for some reason their store takes a LOT longer to load than steam. The game library UI is much worse. Pretty sure there's no easy way to mod games through the epic store or see dev updates or talk on a forum or submit bugs. Just so bad.
