I do think your hypothesis is unsupported. I have little reason to believe there's a 90% correlation between the two, there's certainly no evidence of it.
It's possible that you're basing your hypothesis on anecdotal evidence and self-selecting groups (like enthusiasts on internet forums).
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
