An interesting snippet from the article: At IndieCade in October 2011, Adam Saltsman, Canabalt's creator, discussed the notion of "time until death." All of us have a finite amount of time on earth, and any time we spend on a particular activity is time that we can't spend doing something else. This means that the time we spend gaming represents most of a game's cost of ownership, far more than any money that we spend. If that time is enjoyable (or rather, if its benefits outweigh its costs), then the game was worth our time. I think this is an interesting perspective. Personally, I don't calculate opportunity costs except at an intuitive level, and as a result I'm probably getting it wrong.
