How many plays of Pandemic Legacy until it is complete?
The Pandemic Legacy campaign runs over a single year. You play a game for each month, but if you lose then you play that month one more time before moving to the next one. So if you win every game, you will have 12 games, but if you lose each month then you will have 24. Before you use any of the Legacy components, you can also play an unlimited number of games of "standard" Pandemic (or something very close to it), but once you start opening packets and putting on stickers you're in for those 12-24 games.
