It's really not that hard and there are plenty of guides available. If you are unable to visit the "store" (discovery), download a program and finally run it, then maybe you should just keep using Steam and not complicate things.
I feel like if you are smart enough to know that Heroic Launcher exists then you could figure out how to do a google search on how to install it. It's not like Windows "just works" every time
No I just think you're exaggerating the problem and had a bad take on it. In my opinion Steam is harder to install on Windows than Heroic Launcher is to install on SteamOS.
Messing with Proton isn't required and I am sure most games will figure out how to add a shortcut to Steam.
installing HGL or any other launcher is going to be both inconvenient and require a level of investigation that most people don't care to bother with when they can just hit "buy" on the store.
This reads to me that think Valve are going to make installing shit harder. I'm arguing that at the moment it's easy to do and Linux is an open platform. Nothing like a walled garden
Alright, I guess we'll just agree to disagree. I think Valve has done a fantastic job with the Steam Deck and I love it's openess. The Steam Deck made me aware of how good Linux has become and is the reason I ditched Windows on my desktop computer
