I bet they would if they could, but keeping the game server up and having someone maintain it costs money. If anything they should drop the F2P and just charge like $4.99 for it and goes on sell for like $1.99. I would buy it.
I think they will do something for those who recently purchased anything in the re-release, but I doubt will get any info until like next year. I assume wont have a new Fallen Earth until late 2020 lol
