I don't get how everybody's going crazy over how great this is. It has a few good moments, but it's basically just 'hunt and click'. Lacks originality and/or humor. I gotta go with 2/5.
I kinda thought that maybe everybody was being too harsh. Then I played it... I kinda think they're right. AI is terrible, controls are terrible. WOMBAT.
The thing that makes this less fun than it SHOULD be is that the disease can be: a) 100% non-lethal, b) 100% non-detectible, and c) minimally communicable, and countries around the world STILL close their shipyards and airports like it's airborne-bubonic-syphillitic-necrostic-birdflu.... and they will KEEP them closed FOREVER?! Lame. We need a new version with a little more realism in the 'realistic' mode.
