Can't speak for others, but I know for me, I've reluctantly passed on several nice 80s Ballys recently because of Haggis. I'm in on Fathom Mermaid because I like the idea of new rules more than authenticity. I recently had people breaking down my door to buy my original MM, so I know other people value original games more than I do.
Not knowing which games Haggis plans to build has put a halt on me buying anything I think they might produce in their 5 game lot. Sucks because I've missed out on some nice games that I want due to pure conjecture. Not sure if this is playing a role in people's perceived price ceiling for your game or not.
I'm getting ready to start selling my Fathom and all the parts needed to restore it to perfection, so on a different level, I'll be with you testing the waters on a Bally sale.
