This group is about having fun making games that benefit the world in some way. So it's important to realize that this group plays games as much as develops them. And as we play games we comment about them. We criticize them so we can understand how well the game is accomplishing some kind of broader goal.
Here's an example: World Peace. How can we design a game that helps people achieve world peace? What areas need to be covered such that people are actually able to learn something about their situation and how other parts of the world have achieved a society that is more peaceful in itself as well as encourages peace everywhere?
Another example: Tech Gap. What are design principles needed for allowing technically challenged people to participate in technical aspects of our society despite limitations due to age, mental ability, physical ability or they're simply impatient?
Another example: Learning to speak in public. A game can give people practice at speaking to an audience, namely the other players!
More: marriage improvement, city design, bicycling, leadership, homelessness..
Notice that I'm not mentioning much about competition and strategy. To me, it's more about process and experience. The better the experience of the game the more players enjoy participating. Games cannot be highly complex if you're interested in maximizing participation. Not everyone is a game geek!
I'm interested in playability, desire, pleasure, happiness, uniqueness, randomness, focus, fun, laughing, high-fiving, engagement, sense of achievement, sense of belonging, sense of time and place, imagination, anticipation, etc.
Anyway this gives you an idea of where I'm coming from.
So what is your cause? What kind of interest and awareness do you have that you can help guide development of themes and events, ie, content?
On the other side of this picture, what kind of game design ideas do you have? What game mechanisms and features are liked by many people and how do they affect its players regardless of content?
