Just over a week ago we discovered that there's a fan-developed Swapnote RPG waiting to be played. Creator Ben Gray has now posted a follow up video with more specific details on how it can work.
This is useful information for those without much experience in pen and paper RPG games, with examples given for the player simply navigating through rooms and battling with monsters. If you're planning to be the dungeon master, for example, you'll need to track down some dice; the more sides the better.
As made clear in the video, this idea is based on an honour system with trust between players, and can ultimately be adjusted to suit each group's needs. The latest video is below, with illustrations and files available on the video's home page.
