August 21st) Which RPG does the most with the least words?
Another question I could look at in two ways.
At face value I can point to games with fairly minimal word counts that generate a lot of options & value for play. In this case I'd have to go with Microscope. It's literally both a game and a world engine. One of these days I really want to kick off a campaign by running a few sessions of Microscope ahead of time with my players to cooperatively build the setting.
Alternately I can look at this as what RPG does the most with it's art. In this case using art to help sell the setting, tone, gene, feel, and the like. This is hard to pick just one as art can really speak to you in a way that words may fail to do so. Games like Deadlands, Dark Sun, Gods of the Fall, and Rifts (yes, even Rifts) all contain artwork of such beauty and composition as to really draw me in and put me into those worlds. Even when the mechanics or setting proves something other than what I wanted that art can stay with me for years later. As a younger gamer the covers of the TMNT & Other Strangeness RPG and its various supplements including After the Bomb all spoke to me with such strength that to this day a few of them remain in my top 10 of all time best RPG covers.
