I can't see Graal being a success on any console, except the Gamboy due to the fact that the majority of console owners expect a little more graphical wise and single player mode out of their games. Graal was made to be a MMORPG and I think it's best it stays that and tries not to go to console. There is very little single player play time in Graal and unless they get a great story writer before they even start making anything else for the game because Graal currently would be awful on a console.
Although the Gameboy project was stopped, I think, is a shame because I think that was one of the good ways for Graal to get publicity and more players.
Attracting players to games like this is rather difficult with all the other similar games which have better graphics etc. There are few 2D gamers these days.
Even though most of the popular 3D MMORPGs thousands of people play, they have to pay a fortune for when Graal is cheap.
