You can't really compare an all time game that everyone at least played once in their life and Graal. Graal is just Graal, and to me with all these rising 3D MMOs, Graal doesn't stand a chance, not to mention barely any server improvement is made. If you look at iEra, when I was a staff we asked thousands of times to get a server upgrade because the server was constantly at 90% CPU Usage, with at least a server restart (self restart) a day, because the server needed to cool down. Not to mention it took Toonslab about 3 years to get them to get our dev server working again.

So yeah, to me Graal should stay in 2D, I don't even think the current servers can hold 3D.
