Personally, I hope there aren't any more versions.
I wouldn't be buying them anyway.
I really enjoy playing Lion Rampant (last played just a couple of days ago) but I think there are enough versions now. For me.
It's not rocket science - anyone could easily come up with their own variation. It doesn't need 'Dan Approval'.
For me, when I play a different game I like to play...er...a different game. Otherwise it'd be like playing chess, only you'll use your Simpsons pieces and I'll use my Star Trek pieces.
When I play a different period I like to play a different set of rules, otherwise I'm not really playing something different. That's me, though.
