Well theres alot of mini game maps in the mini game map thread, but not many of them really seem 'mini' to me. You know, using every single possible object or making it overly complicated'n such.
So, here is Simon Says.

It's a fun game, but you must treat it with respect or it will treat you badly. So if you want to respect it, play it with a good group of your buds and the game will love you and in exchange, grant you fun. But if you play it with a not so much good group of buds, the game will be angered and never give you fun until you play with a good group of friends.

You don't know how to play? I'm sorry. If you want to learn go back to preschool and they will teach you the ways of Simon, because the game plays exactly as it sounds. Except if the simonees(?) dont do what simon says... they either get a bullet in the head, or explosives ON their head. :)

For that one comment that would say, "pics or gtfo" you get AN pic.

~~Portant~~ Make sure your party is closed or on invite only, or your xbox will lolblow up :)

'Sigh'
I guess I could give you a few commands for Simon.

Simon says "Look to your right." (You look to your right)
Simon says "Look up" (you look up at explosives that will soon fall on you)
Simon says "Pull out your magnum" (PRESS Y)
"Look down" (Don't look down)
Simon says "Look down" (kkitssafelookdown)
Simon says "Have a rave" (Pull out your plasma pistol, charge, and dance)
Dance (I cant give you all the answers now)

Get creative

I suppose if you get creative (or evil) you could do trivia.
(Example)
Simon Says "WHAT COLOR IS MY SHIRT!1!!!"
