The "biggest fail" for me was BangDefence. I think quite a few of us in the !PIZZA community got dragged into that under the impression it was developed by HashKings.
Even if they've promised to come up with a new game to make up for Bang's initial buyers, it just means an even longer wait for that amount of $$$ put in for which nothing might even come out of it.
Lesson learnt.
Ohh. I invested a little in Bang Defense too but thought it was just not done yet. -.-
What exactly happened to it?
