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

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).

Played multiple times at Washingcon. Honestly, it's better than Pandemic. I love all the changes, and I prefer the theme. Unfortunately, I don't have the kind of group who'd appreciate it - the ones who prefer simple games would just want to play Pandemic, and the ones who like more complicated games are sick of the Pandemic formula. But me, this is perfect for. I'm seriously considering buying it just to solo.
