I haven't gotten much of an opportunity to play with this mod yet but I've scoured over all the additions quite a bit and I'd like to raise a few concerns.
1. India's Mughal Fort: '+1 City Defense for every World Wonder built in the City'. I was surprised when India didn't retain more of it's increased defense capabilities, and am glad to see it has returned in some form. Now this applies for all world wonders in all cities correct? Meaning if you have all your wonders in your capital any city with this building will recieve the additional city strength? Comparatively speaking this ability seems pretty situational. It requires alot more effort (and luck) relative to Greece or Netherlands UB, and due to the limited amount of wonders in regular games this ability is unlikely to scale as high. Would you consider buffing it +2 City Defense for each World Wonder or adding National Wonders to the list? City-exclusive would be interesting as well, and unique.
2. Iroquois Sachem's Council: I'm curious as to what the main goal of this UB was. It looks pretty solid in generating additional resources for the capital and afaik is a unique mechanic in VP. I should tell you I haven't actually played the Iroquois in VP, or even in vanilla for that matter. Part of the reason for that is to me, on paper, the Iroquois look to be one of the weakest Civ's there is, there was, and ever will be.

Oddly enough though the AI always does pretty damn well with this civ.

Though really, they have a good early military advantage and beyond until you deny them forest and jungle. Outside of that they don't have a clear preferred victory like most of the other civs do. Now despite replacing a diplomatic building, between the additional culture from the building itself, the potential of the promotion, and their other UB, I could maybe see them going for a cultural victory. Overall though, for a national wonder, this looks pretty weak and doesn't do much to push them towards a diplomatic victory. The promotion itself, as far as I know, wouldn't contribute anything and +2 great diplomat points isn't very noticeable in the grand scheme of things. Keep in mind the Iroquois, outside of a little extra food, don't have anything to contribute to the generation of great people, which I would say both culture and diplomacy is/can be pretty reliant on. Thoughts?
3. China: I feel I have to mention this especially because of 2 up there. You thought China was crazy before? You ain't seen nothing yet!
4. Japan/Brazil/Others: I'm not so sure it's such a good idea stacking bonuses like this. These civs, especially Brazil, already have amazing tourism output. This applies to other Civs as well, particularly science ones, and science at least has an easy catch-up mechanic. Most of the civs here got something that would push them towards another victory they otherwise might not go for, or something to make one of the victory they could go for more viable. Some of them however did not.
5. Venice: I'm a little confused here. So they have 2 naval range units in the same tech? I imagine then they upgrade into the same unit. I really can't speak on whether or not you'd want to use both of them until I actually play them, but, and correct me if I'm wrong, you'd be encouraged to go with the Fusta for the potential carry over of the promotion no? The other ship in comparison doesn't have anything going for it other then being stronger at the time. That seems a little off putting.
6. Ottoman Bombard: Essentially a super unit that's very strong for it's time though kinda like above, I'm a little worried about when it upgrades. It would appear it keeps the Sahi Topu promotion so I assume the idea is, for two units only, in exchange for the Sahi Topu promotion you get two other promotions. I generally like mechanics that promote additional interaction but I'm not convinced that's a fair trade. Maybe it is on the bombard, when at it's base it's nearly 50% (?) stronger then cannons and comes one tech earlier, kind of disturbing actually, but beyond that I think one might be tempted to scrap those two units for regular siege units that aren't as prone to being one-shotted due to the loss of health from firing.
7. Babylon Sabum Kabitum: Is the legacy promotion lost on upgrade? Because that's 75% combat strength at level 15. 40% at 10. With that kind of scaling their spearmen will overshadow anything else they might be able to field.
