Incentivized interaction is not community, it is business. I am in a FC with a great group of people who roll together on all kinds of content and have a great time doing it. I play content that I currently have no use for just to help others out and build stronger bonds with my mates. While I see your point and understand where you're coming from... I think you look at the merits of mutual benefits as a solution to build community, and it isn't. Mutual benefit is what DF and roulette give us. A group of people we can use for mutual gain and then forget about for a week or so. Philanthropy builds community and this is, and always will be a choice.
