Well, i'm assuming the idea is that players could attack one another, in hopes to get to the end the fastest.

I think there should be a game/event similar to Battle Online, which is owned by Eurocenter aswell, so I think they would gladly incorporate it into Graal.

If you don't know what it is, here's a link: http://www.eurocenter.fr/BattleOnline/BattleOnline.html
