I pledged for the game and expansion. Totally worth it. And I haven't been in the mood to pay full retail price for a single game in a long time (other than Torchlight!), I'd always wait for a deal... and hilariously enough, I'm willingly paying extra for the couple of games coming out on kickstarter without regret. And PE reached every stretch goal and some more so far. Not sure if they'll add one more as there are only 12 hours left... but they did already pass the last goal of 3.5m by almost a 100k already and it's not slowing down.
I just wish Shaker would get some attention afterwards. I really love their concept, but their initial start was a bit too vague and they're having trouble keeping up. Hopefully it'll pick up once the PE kickstarter ends.
