The official answer was this:
As a consequence it seems clear to me that waiting for the possibility of international projects with Kickstarter is a no-go. It probably won't happen soon for whatever reasons.
This is very sad as to me it truly seems that crowd funding with Kickstarter currently draws much higher donation amounts than with other platforms.
Well... it's time to try changing that if Kickstarter doesn't want an ADOM crowd funding initiative. So we'll be preparing the "ADOM Classic New Version Fundraiser" for Indiegogo, even if that platform seems to get about 10% of the exposition of Kickstarter.
So soon we will see what the future for "ADOM Classic" might be. If we raise enough money, we'll see new releases and new versions (not to mention the iPad version and maybe even an Android release). If we fail to raise enough money... well... things look bleak as time is a highly limited resource and we (Jochen and I) need money to buy time. But we'll see - it's too early to judge. We'll keep you updated about the progress with campaign preparations and then it's going to be a very exciting time for us. Afterwards we might consider an ADOM II fundraiser, too, but that depends on how much progress I manage to make without it and if I succeed in getting ADOM II Deluxe out without extensive external help ;-) I'm trying my best...
