The update also includes information about slots being opened up for the higher tiers. So, if you've been holding back because you wanted to back at one of the sold out higher tiers, you're in luck, as more slots have been added to these tiers. Go ahead and grab them quick if you're interested (there's some neat goodies in there, like getting to voice a character named after you for $300, or if you have some money to burn, having Bill fly to your house and paint a mural on your wall for $10,000).
Of course, the most important incentive is that if this is funded, you'll get to watch Jason reenact the Melee Island wedding scene, and watch me perform the Curse of Monkey Island pirate song. So, go ahead and back. You know you want to.
