- A game in which player characters roll dice, kill monsters, collect treasure and advance in power.
- A game in which players pretend to be avatars, interacting with each other and in-game beings in order to pursue goals which require overcoming obstacles in order to achieve victory.
- A game in which players investigate the limits of their own abilities by attempting to establish social or economic frameworks of their own design, as a means to organize or develop concepts they've created upon the backdrop of a quasi-real world that seeks to promote positive and negative feedback for their efforts.
- A game that forces players to question who they are, challenging their belief systems while psychologically re-engineering their habits and expectations in a world that fails repeatedly to correspond with their wishes while simultaneously tempting them to further flights of fancy.
