Nothing more disappointing to me than seeing a game I might enjoy… and then it’s only available on PC on Epic Games store. Why can’t it be available on Epic, Xbox game store and Steam? It’s so annoying, like you have no choice but to use Epic… which I would literally do ANYTHING not to use.
Depends on the game developers, if they offer/upload a Linux/Mac version. On Linux, you have to either install/update your games manually, or use a third-party client. Idk about Mac. Third party clients can also integrate Wine for Windows games.
You don’t need to update them manually if you installed them using Heroic. You only need to update them manually if they were manually installed using a offline installer.
