Hello, personally it took times for me to find how to install a game.
I mean that I didn’t know that it was required to download an install item from the site.
To install starcraft2 I downloaded starcraft2 install file from lutris.net and launched it/
I just saw that that by clicked on the magnifying glass button, I could more easily install program.
I suggest the programmers to add a link in the add menu on the top left on lutris windows before “add games” and “import games” which would say “install games from the list” which would by clicking on it act as clicking on the magnifying glass button.
Just a suggestion, don’t know if it’s a good one.
