From the campaign:
The Keyring RPG is a combination of an idea about a flexible role-playing game and a passion for paper crafts.
The Keyring RPG is a combination of the idea of creating a procedural role-playing game and the discovery of a really cute notepad. Mashing those ideas together gave rise to the Keyring RPG.
Key features (no pun intended):
The Basic Game is very small, only 7 x 3 x 2 centimeters. You can carry it on your keyring.
It features a procedural adventure building system
A full rules set that allows for a lot of flexibility when playing
Five sets of generic maps
The campaign's a bit more than halfway to its goal with still 13 days left to make it the rest of the way.
