I don't think Fonzie is a "scammer" in the classical sense--I think the work he put into Paprium is enough of a testament to that, but I do think he has no business starting up a new project while Paprium is still floundering in the wild with unfulfilled orders, crippling incompatibility issues, and a significant list of as-of-yet uncompensated co-workers he exploited and then alienated.
The hoard of Paprium issues aside, this new project itself is so glaringly suspicious in its conception, I have a hard time believing that some European trade or consumer organization isn't going to step in. It is simply reeking with avenues of crowd-funding exploitation, and I cannot imagine the kind of person who would willingly fund a "mystery game" from someone with Fonzie's track record?
I guess P.T. Barnum was right...
