You also still have games that don't even have any official game servers : Factorio for instance, and I guess "classic" modded Diablo 2 could be kind of considered to be it too since mods were never allowed on ("closed") Battle.net, only on "open" (not-)Battle.net ... (which IIRC only does matchmaking, while it's the player hosting the game that acts as the game server ?)
And Factorio has people setting up (usually renting in data centers ?) dedicated servers too (which then are at least accessible to everyone, unlike non-dedicated server games hosted on home networks where people not even bother to properly set up port forwarding any more, forgetting that not everyone relies on Steam to do the job for them...)
