I don't really prowl this forum (forgotten my ID/password) but thought I would contribute.
Firstly, this is an excellent approach, FFG, very inclusive and consultative, and the basic concept (provinces hold rings) is very nice, a clean implementation of the Enlightenment victory legacy. I am stingy with my praise but this adopt and core idea is very good, even if it needs to address various issues as I see it.
I'm going to be very lazy (late here in the UK) and link you to my alter-ego's post on cardgamedb (the relevant posts are #7 and #10 in the thread).

Hope this may have contributed positively in some way and good luck with the development.
