It's amazing how I managed to ignore this article for so long.
Playing and Gaming: Reflections and Classifications, by Kampmann Walther, discusses the differences and connections between those two distinct kinds of ludic activity.
Here is a selected passage (the emphasis in bold is mine):
"(...) gameplay should work to assure the circularity of different orders of complexity without doubting its own make-believe. Gaming should not be troubled by playing. Rather, we should be concerned about finding the most sufficient and entertaining way to proceed appropriately."
Interesting. Could we say that, in a way, playing should also not be troubled by gaming?
I found about this article on this Wiki, which kindly links to nongames.com and my MA project at Gamasutra, amongst other articles on toyplay, creative play and related subjects. The wiki is called Knights and seems to be a Scandinavian educational resource website. If anyone knows more about it (I can only guess the obvious words, such as Kalender and Artikler) please let me know.
Well, that wiki is a great resource for play and non-games research, so I thought I should place a similar list on this website, which is now located on its right side. It lists books and articles on the subject (some links were borrowed from Knights, and I hope they borrow some from me as well).
I am also thinking of adding a list of non-games - I have posted on many during this months, so it shouldn't be hard to start it.
I will welcome any suggestions from you, both for the resources list and the games list.
