I really like GOG, they make older games easy to play on Linux. They even have extras in some games I’ve bought, like that Fallout 1/2 app for fixing bugs and upgrading graphics etc. It’s super fucking annoying they don’t have a native Linux client, the main reason I don’t use them much, I also want to play old games on my shitty Windows work computer too, but it doesn’t sync saves with my awesome but not powerful ThinkPad at home
i’d suggest using your own instance for that
