I’d also love to replace the Steam client, but both Lutris and GameHub require it to be installed to work. Out of the two, I I’d go for Lutris. It has much more active development and has it’s install scripts feature. I also have a lot of games on itch.io and would love to ditch the Itch electron client. GameHub has Itch game support whilst Lutris is still planning on implementing it. The problem that I have with GameHub’s implementation is that the games library is refreshed every time I reopen the app, instead of just caching them and having a refresh button like what Lutris has. This means that I have to wait a good 40 seconds every time I open it to be able to access my library, and it’s still really slow to get game thumbnails. It also doesn’t have a flatpak, so it’s a pain to get on Fedora

The thing with lutris and gamehub is, that they do not replace steam. It drives me mad that they are considered game launchers, and I guess it is true if you buy your games from gog, but if you have steam games, lutris/gamehub is pretty much steam launcher, not a game launcher.

They make stuff simpler in a way though, like gamehub and lutris both enable gamemode by default, while if you only use steam you need to set manuallu every game to do so. But idk, it still feels much cleaner to me than using gamehub to launch steam which launches the game.

Any games you already own on Steam or Epic will still need to launch those clients in order to run with GameHub. If you run Linux, then a lot of the work Steam does in the background with Proton to make things run will no longer be automatic.
