A scam is by definition something with malicious intent, something dishonest, and I think that's why the other commenter took offense. It might not live up to the hype, and maybe it'll be lackluster, who knows - no one has played with it yet outside of Panic. But I think it's fair and not disingenuous that the other commenter took a lot of offense to using that word, because by all accounts it doesn't seem to be a scam. I would find a better word that doesn't imply malice.
