while fallen earth was running it was slowly dying from the lack of playerbase, the exploits, and the gameplay quirks. getting shut off was its best chance at coming back better. I think its best chance now would be to bring back sector 1, with a wipe. one tier of bloodsports, 2 or 3 pvp zones, a new economy that can be fixed with a new sector in the future if it gets broken, and enough material to rp with. plus a smaller game for the limited playerbase.
get the ball rolling from there, keep working on fixing the many problems the game has right now, and fallen earth might have a few more good years in it.
