A friend of mine is creating a multiplayer dice game. The game rules are currently designed for 3-5 players, and don't require much of an investment for the PnP to create the necessary components. Only a 30 card deck needs to be printed, a lot of dice, and a pen and paper to keep track of score.
He has been struggling to come up with a solo variant, because he believes that a large majority of the PnP community either plays PnP games solo, or most PnPers like to try out the game by themselves before bringing it to their group.
This got me to wondering,
If you don't have a solo player variant, is your PnP likely to get played?
Do you also need 2, 3, 4, ..., player variants?
What is the optimal number of players for a game? Is the number of players that will play a PnP designed for 1 player the greatest, and as the number of players increases, the likelihood to find people willing to PnP decrease linerally (exponentially, or does the graph look like a bell curve?)
