How "unique" you're argument is, bares no relevance to my dislike of it.
Um, okay.
Then why use it incorrectly?
Because I didn't use it incorrectly. The preview thread for this NES was an enormous undertaking which included the involvement of many prominent members of the community that promised
a lot in terms of NES quality, promises which I do not feel were fulfilled in the actual execution of the NES. Birdjaguar himself asked, for example, for some historical research by all the players for their respective polities in the interest of modeling factions. In relation to the rest of the NES, the time and attention spent on promoting it or discussing it is an
ostentatious display.
As for arguments of "historical accuracy" or lack thereof: I feel, as a NES purporting to originate from OTL 1490, that Birdjaguar made a good faith attempt to make it as historically accurate as possible at the origin point (save for design choices such as the alternate Americas) and make it as historically
conceivable as possible thereafter. Unfortunately, due to lack of time and/or pre-established knowledge base by the mod, this was not satisfactorily fulfilled in many crucial parts of the NES. I myself was frustrated by the vagueries and incongruencies found within Central Asia which lead to my dropping of the Safawiyeh, and I have heard similar complaints with regard to England, India, the Levant, and Iberia, amongst others.
Birdjaguar meant for this NES to be a complex and serious NES. The "simulationist" trappings of the complicated stat system are obvious when you look at how deeply and closely it attempts to model various aspects of polities. I do not feel that this NES was meant to be light and casual, although perhaps it is headed that way after all given the changes in the player base. The problems with the black box, as others have stated, arise not from the opaqueness of the numbers, but the inability of players to determine cause and effect between changes in the stats at all. There are many simpler simulationist stat systems, including in one NES set in a similar time period as this one, which have been much better received by players overall.
I feel compelled to address these issues because Birdjaguar did comment that he felt decaying interest in this NES, which is certainly true, and because of the variety of issues associated with this decay. I do not have any issues with Birdjaguar as a mod in general, but in my opinion this may have been too ambitious an undertaking given his current ability to invest time in NESing, and explains the loss of interest by certain players.
