One of the topics I have been working on for a while concerns hedonism as a moral philosophy of gaming. This is, of course, frightfully ambitious, seeing that I am not philosopher. I am certain my arguments can be ripped apart quite easily by somebody who have actually studied philosophy, and not gaming. If so, feel free to find my article The player as hedonist in the Journal of gaming & virtual worlds. But for those of us who are more concerned with new ways of thinking about games and game research, I am trying to poke some holes in the idea that pleasure can be planned and designed for.
A counter-productive claim, if you are looking for a formula to make winner games, but if you're trying to gain insight into the wider processes of gaming it's very important to keep looking for different viewpoints. And so I have thrown one of mine out there, going out on thin ice for the sake of trying to carry an argument across.
