This was a good game, but having several that use the pandemic mechanics we chose to keep a few with the themes that appealed to us most.

Very similar to vanilla Pandemic, with a few Cthulhu-ish twists. The flaws in the game are too similar to base Pandemic for my tastes, though (complete reliance on shuffle, little or no ways to influence that).

My version is in portuguese because we couldn't find it in English gere (and we had a gift card to use) but the game is awesome! We've made 4 games (2 players) since we bought it and we are tied with Cthulhu (playing with all cards) :P
