@Shachar_Weis I’m sure there are a few, but there have been a number of them that fail in more interesting ways than others. By far the most interesting I’ve ever run across (but not backed, luckily) was Katalyka.
If you’re up for an hour or so of bizarreness, try reading through a couple of the forum threads about it on boardgame geek: http://boardgamegeek.com/thread/826968/game-update
The short version is, the creator appears to be an untreated schizophrenic who is refusing treatment, and this has taken something of a toll on her ability to complete the game.
The part that makes the story enjoyable, for me at least, is that everyone has (for the most part) managed to avoid turning it into a hate-on-the-mentally-ill festival and has given up on ever seeing the game. Now they’re just sitting back and watching the bizarre reality of this thing unfold.
I’d definitely say it’s worth a read, just for the sheer weirdness of it all. Anyway, sorry for the threadjack, I have no doubt the creators of this project aren’t clinically insane and will in fact deliver a 3D printer as they promise.
