Host Game Idea
You wrap an item in your inventory and send it to yourself so you can trade it away. The Hosts have wrapped items as well, you all do a one time trade. Simple - and a surprise as to what you might get. If people can refrain from having to have an entire conversations with the Hosts it might go pretty quickly. The Hosts can surprise us with great items and duds, luck of the draw!
Another idea i had was lucky chairs. If VFK could create teleporter chairs, we all stand behind a fence/wall/barrier whatever and they say go/open the barrrier- everyone grabs a chair - some will lead to a prize (teleporter room?) , some will not. This one would go fast if everyone could get in and not be afk in the doorways. They could maybe put out like 20 chairs. Easy enough for them to move the winning losing chairs around..
