This is not really a Lutris issue.
Last week Epic gave away Subnautica for free.
I used Lutris to install the Epic Game Launcher (& opt out of beta) and then installed and played Subnautica.
Tonight Epic are giving away Super Meat Boy ( I know that I have it as a Linux native game in Steam).
(It looks like a game giveaway every two weeks.)
If I open the Epic Launcher I only see the main game tabs at the top eg Fortnite …Subnautica etc
How do I see my Epic games library ?
From the browser with epicgames.com I can click on Super Meat Boy - Install , it then says to download the Epic Launcher.
Does it need a new Lutris installer to install Epic Launcher + Super Meat Boy ?
