But I think there's a separate ethical problem, about "why them and nobody else gets to ignore the rules set by Kickstarter itself".
This is my biggest deal. The way I see it, there are two kinds of kickstarters generally. There's the more common "I have an idea and want some money to start it from scratch kind" and then the "Here's what I've done, I need money to do more of it" kind. Doublefine Adventure or whatever it was called would be an example of the second kind. This pushes straight past the second into "We're popular, we'll do good things with the money. Trust us." All kickstarters benefit from popularity, but some put far more weight into their popularity than the actual value of their ideas, and the PA one is pretty much 100% popularity.
And I'm still bothered by the fact that they've been discussing and hyping kickstarter for some months to their fans, with the various kickstarter comics and blogging about kickstarter, and now they're funneling all that into getting money for themselves.
I mean, I guess you could argue that it's perfectly logical for them to use kickstarter since they like it so much, but the fact that they've made a kickstarter that's going to run nearly 100% on existing popularity and kickstarter hype rather than their ideas feels a little off. I'd be more understanding if it was a situation of "Hey, kickstarter is great for launching ideas so I'm going to launch my own off it" but that's not really what it looks like to me.
