Your Source for 'Ff'lo

The basic Credo game only requires a few hours to play, and perhaps thirty minutes to grasp most of the nuances. The subject of the game, the Nicean Councils which established the Christian Creed (the whole "We believe in one God..." schtick), might require a weekend to research thoroughly.

Gather your bishops and secular leaders, refute the doctrines of other sects (your fellow players), convert the pagans (or watch them martyr one of your bishops), persecute sects whose doctrines are at odds with the Credo, and rally to hold off the latest wave of Islamic invasions. What fun, eh? :)
