Hello. First, I would like to say I really like this map. Played with it in the tPatT mod and now I am playing CK2+, I find I really miss it. However, I can't say I am fully satisfied with the mod either, having found a few issues that greatly bother me. As such, I am taking the liberty to post here my criticism and questions about what I find to be some of the questionable decisions about the map.
First, lets start with the cultures. They are all over the place. Some places, like catholic Iberia and Italy, were heavily fractured in tis cultures, where other places, such as Germany and Russia, remained monolithic. This seems very inconsistent to me. There was really such a greater difference between a Tuscan and a Lombard, when compared to a Bavarian and a (Germanic) Saxon? In fact, I may be wrong, but I believe there was no great difference between Galician and Portuguese for most part of the time frame, so splitting them seems somewhat wrong to me. At any rate, this makes the culture set up seems artificial to me.
Furthermore, a some of the new cultures seems rather pointless, at last in the earliest start date. Bosnian, for example. There isn't a single Bosnian ruler at 1066. And since it is already a fairly small culture to begin with, it is very likely going to be simply replaced by the Croats eventually. Most of the Iberian cultures have the same problem. They do have some rulers to offset the problem, but they will likely never expand through the game (as they did historically) and only become smaller, due to the dominance of the Castilians.
In the end, I have to question what the gameplay purpose they serve. Is this extra foreign opinion malus going to change the game for the better? You can't say they make the game much more historical either, since, due to the game mechanics, many of the smaller cultures will never follow their historical progression. As such, I believe there was simply too much new cultures. They probably could use some timering, to see which ones are worth to keep and which should be merged together.
About the de jure set up. It is good, as far I can tell. I particularly like the de jure Papacy, although it seems to be broken, at last on tPatT (it is not the same title as the one the Pope holds). If I had to mention something, it would be about the amount of small de jure kingdoms, each with one or two duchy in each. Wouldn't make more sense for them to be titular kingdoms instead? Kingdom of Bosnia, was only created near the end of the game, so I believe it is a tad weird to have them on the map since the start (not to mention the high probability of being assimilated by Croatia, anyway).
Another thing about the de jure kingdoms is Germany. Not really a criticism, as I have currently no opinion about it, but why partition Germany into kingdom level duchies?
A minor thing but that really bugged me is the impassable mountains on Iberia. The original impassable mountains are really impressive mountain ranges such as the Alpes, but in Iberia, it seems every hill is impassable. Considering it is just there and not anywhere else, it seems very weird. It also makes the names really ugly around there.
Well, I think this is it. Sorry if this are issues that have been already brought before, but they were things that really bugged me while playing. Again, other than that, this map is really freaking awesome, so don't take it the bad way.
