Just to clarify, you don't need to know zip about Cosmothea to play. This is an uber-lite version of the game or rather uber, uber lite - you can create a character in no time and be up 'n running.
for an exciting scifi adventure? Project: Valhalla starts off adventuring in a high tech region of space, but you can run mages, superheroes, whatever you want, joining the team going on an adventure to uncover the mystery behind the missing recon ship and missing passengers of the Valhalla. Fun stuff, I promise! And, if you'd rather dive into a fantasy adventure, we've got that covered too, with No Turning Back.
