Looks like a great game indeed (and the SE might be a genuine bargain), but let's not get ahead of ourselves just yet!
Looking at it objectively, it seems as if it is more "evolutionary" than "revolutionary"; I imagine it will ultimately land somewhere in the top 10 on the "charts", but everyone is in the new pin honeymoon phase at this time and it is probably a bit premature to declare that it will finally be THE pin to capture the top spot. (At this point, I still hold the opinion that JJPOTC remains JJP's high-water mark, but of course this is subject to change when I finally get a chance to play GnR.)
