I think you are wrong, but I also don’t think there’s much evidence to be had either way, or much hope of swaying each other. A game like this will either be made or not, and even if it is we’ll still be able to argue about whether or not it is actually any good. :)
FWIW, after bouncing the idea back and forth a bit, I’m more hopeful than ever, so even though I wasn’t able to convince you, I hope you enjoyed it as well!
