oh awesome, I totally wasn't around for the last PGD and I totally want to be part of this next one. Are we talking 1D? because if it is I've got an excellent idea for a game, I call it 'line'. The object of the game is to move along the line meeting other 1 Dimensional characters who ask variations on the question "Do you think higher dimensions exist?" at which point the player has to select from range of responses that reject the notion of higher dimensions as pure fantasy.

Once a suitable response has been given, the player continues upon their journey, safe in the knowledge that they'll never fall off anything.
