This is one of the greatest, most awe-inspiring things I've seen in quite some time: a chart that lists every possible thing that could happen in a given turn of Cosmic Encounter. It's so thorough that it goes way past the actual concept of "thorough" and begins to loop back around toward the idea of "over the top." I especially like how it makes CE seem to have a more vertical learning curve than Arkham Horror.
It's a must-see, trust me. Bang that link.
