My point was that you assume he is doing this out of pettiness, while I assume he is doing it out of necessity. As far as I understand, here is what I think happened:
First, they could either release this kickstarter now or further on next year. I don't really understand why releasing a kickstarter during Christmas would be a bad idea, but let's assume that is true for the sake of the argument. If they waited, they could have worked on the pitch, made their ideas more throughly explained and think things through some more. Make better rewards for different support levels and get in contact with a few gaming sites like everyone in this thread said they should have. This is so obvious, I assume the reason they didn't is because they couldn't. Maybe they don't have enough money to keep their current set up running, or maybe some other thing I have no idea about (I mean, it is none of my business what problems he may be having or not).
Well, if his team is separating soon if this fails, or won't be able to keep working on whatever they want (maybe they will sign a long contract with a publisher or whatever?), then it is out of his hands relaunching the kickstarter. He wouldn't have much more to show than he has now in a week or two and more than that might be too late. Compounding with all this, he seemed reluctant on advertising features he wasn't so sure about yet. The whole card game thing, which he seems to have a good grasp of in his mind, but is probably untested. Also, I think he hasn't thought of it through as much as he would like. I am hoping he still wants to make the results of each attack, defense and action somewhat real, instead of completely abstract, and bridging systems like this is a tall order. So he withheld a lot of information from the original pitch. I agree, this was a silly move, after all, without much information, it is completely impossible to know what kind of game this wanted to be. Even PE and Wasteland 2 managed to give you an idea by mentioning their antecessors, but it was clear from the get go this wouldn't just be a straight Realms of Arkania game. But still, if I was in that kind of situation, where my two options are either going for broke or giving up completely, I think I would have done the same as Mr. Henkel.
Of course, I may be completely wrong here. Maybe Guido was really just lazy. I don't know that for sure, but I usually try to imagine the best of other people. So, assuming this is really the problem, we have each to decide what to do ourselves. I think RoA was such a great game that I will gladly pledge to this kickstarter, and I will try to convince others too. If you didn't, or if you think Guido is being malicious here (for whatever reason), then sure, you should withhold. I just don't think that is the case.
