21st century games: the villains are modeled on the swine flu epidemic.
Angry Birds, I thought.
Then I thought: wait, he said swine flu, not avian.
And then I thought: I'm not even sure they're the villains.
And then it was time. And I was sure I was wrong (I've never actually played it).
But obviously my sister's description of the game had stuck with me subconsciously. The birds are the heroes - and the villains are pigs.
