I just found this game the other day and it's pretty addicting. Seems like a lot of people are on it all the time too.

It's a risk type game although simplified with just dice. There is single player version to practice on called Dice Wars too. Thought some of you guys might like to check it out. My alias is DeathbyDice if anybody sees me and wants to truce for some games >
