I hope it is just the disappointment of the news, not lack of support.Wow, this community really turned suddenly nasty against Trapdoor the moment the licensing agreement with WotC ended. I wouldn't blame them if they never posted here again.
It would make sense that they would need a Kickstarter. Dungeonscape was internally funded, and I'm guessing they were expecting to be pulling in revenues from Wotc by now to offset their expenses and be able to finish development.
