I don't think it makes sense to give a faction slot to the Maccabean Kingdom. As has been stated on the EB1 forums many a time, it doesn't make sense from a gameplay or historical perspective. In terms of gameplay, they would almost certainly be crushed by the AS or Ptolies within the first 10 years, meaning that unless the player is playing them (or the AS or Ptolies), you're never going to even see them. Historically, a Maccabean Kingdom would be content with controlling the Jewish homelands, and would certainly not have any interest in building a huge empire, which is what would happen if they were controlled by the player. They are best represented by strong rebels and an especially rebellious population (which will be much better represented in EB2 due to the "people" buildings and the inclusion of more religious aspects).
