I apologize for the delay in replying. I had forgotten how long it takes for me to memorize the native terms and reread the updates to fully understand it all. Hopefully that'll get easier and I'll learn some of them.
Onto actual commentary.
I'm seeing a few things that stand out in the rewrite compared to the older version, common events are a bit clearer to follow it seems to me but at the same time the addition of the scenes with the Tlaxcalteca(I'll discuss them more later) show something I did not recall from the original version regarding the chaotic and divisive nature the Guerra del Indies taking on. The Spaniards are not particularly liked by just about anyone, but grudges and memories are long and the different nations aren't completely willing to forget them just yet, so there's intra-Indian and intra-European fighting going on that muddles up the whole thing quite a bit. The plus side of that, of course, is that the instability makes Spain desperate for whatever accommodations it can get from its "loyal allies" and/or "honorable soon-to-be-former enemies" to hold onto what they've gotten.
Which brings me to the Tlaxcalans. They're shaping up to have a very interesting future in this new version of Mexico, taking reigns of power and influence in Mexico for themselves through their past loyalty and continued (albeit opportunistic) alliance to the Spaniards. They realize that, aside from the Spaniards, the next spot on the Mexica shitlist is them and are acting to nip a threat in the bud while addressing the issues that have "poisoned" their "strong alliance" with the Spaniards. I have to admire Lorenzo's shrewd ambitions here, though I have the feeling he's not going to get things exactly as he wants as time goes on. In particular, the followers/sympathizers/beneficiaries of the Aztec/Maya alliance and Emaranado are likely to be even more resentful of the Tlaxcalans and their new(or regained, I suppose) status as major power-brokers of New Spain.
Of course, I could be completely wrong in my reading, and if so please feel free to correct me.
