But that's not unique to paid exclusives. That's not even unique to Epic, Valve's own games are exclusive to a single storefront. You should boycott them for the same reason.
There is a cost to releasing games on multiple storefronts, forcing games to release on multiple stores only hurts smaller developers. Some smaller developers also skip storefronts altogether. Minecraft and Factorio were initially sold without any storefront. Is that still considered limited to one and therefore an exclusive?
>Besides publishers are already free to decide where the games they publish go or don't, so I'm not sure where the "too much power to publishers" thing is coming from.
I'm talking about cases where the storefront doesn't want to sell the game. Say the game has adult content, or the game has is just unfinished and not good. If storefronts are required to carry games. Otherwise games that only get accepted to a single store will continue to be exclusive to that single store.
Same thing with smaller developers, are they expected to cater to the whim of multiple storefronts to be able to release a game? One of my favorites, Zachtronic's Opus Magnum was rejected from GoG initially.
