Valhallions got a Kickstarter campaign underway for Superchron, their new post-apocalyptic RPG system and setting.
From the campaign:
Superchron is a fast paced adventure RPG (Role Playing Game) with a completely original and new system. This new system promotes on the spot calls and allows the players to progress immediately and in whatever direction they choose.
The game in essence is a Games Master (GM) led story but with the golden rule of “if a player can justify it they can try it.” The players have dice pools assigned to a number of skills which they roll in an attempt to meet a target difficulty number set by the GM or to oppose another player or non-player character’s (NPC) own dice roll.
