I phrased my reply pretty badly there, sorry! I saw the post saying they could accumulate and that there would be an upper limit, I was just speculating as to whether they would reset on succession. I suppose it depends on what kind of time frame the goals you can spend the 'monarch points' on have. Westernisation is interesting, it of course has to be long term, likely over several generations of monarch. Traditionally this has been tied to technology, proximity to westernised nations and internal government policies (ie centralisation etc). I'd be very disappointed if this was replaced by a system where you saved up an arbitary amount of points and then 'spent' them to westernise. Seems very abstract to say that monarch x contributed to westernisation by saving up 6 admin points, rather than monarch x contributed by closing the technological gap between your state and your neighbour.
The quote I was referring to is from Johan in the Destructoid article;
This seems to suggest that monarch points are for more short term things, building, seiges, good leaders etc. This would allow the game to feel very different from one monarch to the next, a good one spending these points fairly freely while when you're left with an undesirable ruler you have to be extra careful and perhaps reign in your ambitions, conentrating on domestic development or limited warfare. This would be undermined if you were able to store these points long term, averaging out the differences between the monarchs.
