Just by going off the anime so much could be done as far as content besides battling and training.

You could fish, you could race, you could breed, you could enter various other competitions. There's a plethora of ideas for an MMO here, much more so then other MMO's typically go off of.

Really I think this could be a well made game if they spent the time developing it and not just throwing it together like so many other MMO's seem to do with their content. Really I think they might make this if they saw reason so, i.e. enough fan support voicing it. Really if someone got Nintendo to realize the game would have support just from the MMO community let alone the already existing fans of the game itself, they might attempt it. At least if their head guys had half a brain they would see there was money to be made here. >.>
