There's a way to check. Create a computer solitaire game that plays itself while you watch. If it is popular, then just watching is good enough for involvement. If not, then you have to identify somehow with the player. I'm pretty sure some percentage of people who hear about it will just watch: as said officemate noted there are people who pay to watch other people play video games--there are channels devoted to this.
Too much work, too many uncertainties. Though I'd like to see people's reactions :-)
