Whats funny is that most 20 year old multiplayer games today (at least on PC) are still perfectly playable because the server tech was given to the community, at launch. Battlefield 2 hasn't been available for purchase anywhere officially in well over a decade, there's still a dedicated, albiet small community.

I understand that with large, persistent worlds, it's hard to release that server tech, but at least some form of it should be published. Ie, a smaller variant that maybe just lets a couple people join up as a co-op party, rather than dozens of people running around a large map at random, like in The Crew.
