I wish they hadn't hit the $2 million stretch goal. I suspect the DM functionality is going to suck up a lot of resources that could be spent elsewhere.
I too am wondering how much work it will require and whether they'll really have enough money to do all the things they set as milestones. To be honest very few of the latter stretch goals hold any interest for me, but I am glad they have the money. Just hope they don't leave out stuff they committed to do again.
