Any suggestion about Guild Wars eventgames?

Hey! It's my birthday next week, and I want to have some fun with my guild then. But I have no idea what to do, so I want to know some Guild Wars games we can do in our Guild Hall or Exploreable areas. Would be totally awsome

If your guild is big enough you could form two teams and play dodgeball.
The idea was picked up by Anet for the dragon arena... shame they can't make its a random arena option.

Or go as two teams into a match and play a group version of a treasure hunt.
One person drops items and the others have to find as many as they can, speed boosts kick ass

It will sound a bit queer, but use a customised weapon/or drop and play pass the parcel. Or even a "who done it" style game, with the customised drop being the indicator.

Yeah, I heard about that on another forum sounds awsome. I hope there is enough people online on my birthday. Any other types of games? I got suggestions about a Quiz too.

Am I allowed to bump? ;P

As demonstrated at the Ascalon Masquerade Ball earlier this month, the following were popular:

Simon Says
Rock, Paper, Scissors
Trivia Contest
Scavenger Hunt

Enjoy your birthday!
