Here is a game anyone can play. All you need is another person and access to a supermarket. Okay, so I realize some % of the world population can't play this game but you know what I mean. ;-)

Before getting to your chosen supermarket decide on a list of items of food or liquid that you're going to write down. Make sure you think of items that are difficult to find or that are obscure. It is worth actually having three people involved in this game. One person to specifically locate hard to find items, and two to play the game against each other. The one finding the obscure items would write the list and give a copy of it to each player.

The goal of the game is to locate each item on the list and put it in your trolley. The first one to locate and get all items in 15mins (rough time estimate) and come back to a point in the supermarket where the third party is located (he or she could be the same person who wrote the list) wins. :-) If not all the items are found, then the one who gets the most of them wins.

The time aspect is variable and can be changed depending on your particular context, but it does make things a bit more tense because you can't go too fast otherwise you'll bump into other people and the security guard will probably come over and have a little word with you, but if you go too slow then the other player might beat you by finding the items in a quicker time.

For this game you would have to pretend you were shopping like normal customers... just customers who are in a bit of a hurry perhaps? The idea is to blend in to the supermarket environment while at the same time transforming the function of the space through play.

I have not tested this game yet. I haven't gathered the people together. However, as soon as I can then I will test it but I am putting it up here for others to read about and perhaps play themselves. I understand how testing is crucial when it comes to games, so all of these rules are still up in the air.
