> then (with a huge enormous gap) comes Gog
My favourite thing about GOG is that it uniquely does not demand that you install their software, instead letting you download installers straight from the website.
They're not fake netinstallers either, which doubles as a guarantee that I keep all of my games even if GOG goes bankrupt/bans my account/wipes my library/etc.
I was going to say that too. The other day I got annoyed by GoG's app constantly harassing me about updates that I just uninstalled it.
All my games are still installed and still work.
