Add Lutris, as discussed on Discord.
Requires modification to those two write-protected pages:
- Template:Infobox game
- MediaWiki:Common.css (to add Lutris logo, which I uploaded here)
Lutris
I tested it on my own user pages here: User:Faalagorn/Template:Infobox game and User:Faalagorn/common.css Seems to work for me, I placed Lutris as the last icon, but it can be swapped around.
