I like it. I think this game needs some type of social pressure. Right now everybody simply play together in peace, with most conflict limited to verbal insults. The grief is an essential part of any game. We can't be forced to all like one another. We need someone to hate, and that someone is the griefer. And with every griefer comes retaliation. It may get you pissed, but that is the beauty of online interaction.

As for the whole PL argument... casual. One feature of this game: casual.
