I would add the 1999 game Warzone 2100 to this list. Much like Earth 2150 you can design your own units and it also has the persistent homebase + mission outposts system. It was open-sourced in 2004 and has received quite a bit of love since then.

You’re actually seeing mouse pointers of other people having the page open. It connects to a websocket endpoint including the page URL and your platform (OS) and sends your current mouse position every second.

It’s still not a game I would even remotely consider, but is it really bad management if it’s insanely profitable?
