Yeah. Epic delisted the old games. You can not purchase a new copy on any of the digital store fronts, even the single player games. They also shutdown the servers that listed the available open servers. Not the game servers themselves that had map files stored on them. The master server was just a list of IP addresses that cost next to nothing to run. You can configure your install of the games to point to community run master servers, but no new players will know how to do that without someone helping them.
