Seeing the comments here on this sudden change does please me a fair bit. You all have valid points, and reasons behind them.
The fact that they've managed to communicate with ZUN is at least something they can take from this. After all, the project may have been stopped, but I don't see them just plain giving up on this. And if it turns out that ZUN didn't have a problem with the game, just the way it was being funded, then I can see this game in the future for sure.
As far as the get rich idea, I honestly don't think they had that part in mind. Sure, lots of people pledged, but as some of you have said, that's just our fanbase showing the excitement of playing a physical Touhou Card Game in English. Would they aim to make a profit on it? With the GS System featuring original content, maybe. With it being with something that is copyrighted for like Touhou, no; especially when they know about the rules ZUN laid down in the first place. Which is likely why ZUN frowned at the idea of his content being funded by people in something he had no control over.
However, it does bring more attention to overseas. That was likely to be part of their plan in the first place; whether it succeeded or not. It's quite hard to think if they truly were in the wrong or not. One could say they should have got word from ZUN before booting it up; but at the same time, they probably wanted to get something moving if they thought an answer was never going to come. So some patience would have been nice; but they would have kept asking themselves 'would he have ever got in touch if we didn't put it up to begin with?' Not sure on that answer, in all fairness.
But still, props to them for trying; and certainly getting a lot of people excited for it. Heck, they made sure to take on opinions and feedback where possible; and have been updating every night since it started. Even with this cancellation, I can't see this game going away for good. And price wise, it's about ?11 here in the UK from the $20 they were asking for. Certainly cheaper than most card game decks for sure; and more so when you think that this system wouldn't have booster packs to buy with it. So for me, the value is good.
So yeah, sad to see it go; but at the same, I understand completely why ZUN wanted it down. Thanks for chipping in everyone as well; and hope I don't start any arguments and what not. ^^
