1. Yeah, I get that. But if too few boats are floated, I don't really see a point. Though, I can be all too wrong on how many people are eagerly waiting for this.
2. Indeed, but it's still kind of underachieving... It let's us play families which were up until now called lowborn. Also, as far as I see, it focuses a lot on micromanagement.
3. Isn't the new trade system reserved for republics only? If yes, I wouldn't consider it an innovation, like, for example factions were. Factions applied to everything, and not only to the Byz, which was the object of the LoR DLC.
4. I consider SoI and LoR to be "expansions", as they are much more significant than, for example Songs of the Caliph, or African face pack which I would consider DLCs, cuz they are quite optional, and are there to satisfy tastes, not needs.
