Did you see what happened to Trove after it launched on Steam.It had a Million times better server than Graal and it still crashed alot.They needed to do some SERIOUS upgrades to make it even playable.
Due to the major ammount of people logging on,they had to put a queue system and you had to join the 1K+ queue to join.
If Unix is ready to invest some money on it then whynot...but no for now.
