Also, Nakai is apparently a horde-faction, which is interesting. Especially as it's different from the usual horde mechanic. Only Nakai's horde unlocks new units and the others can only recruit whatever he has unlocked. So his horde is by far the most important, giving you sort of a capital horde. If that is expanded upon further it could be cool.
Also, you have a vassal who you can give cities you conquer to. Which is very interesting as that's one of the most annoying things when playing a horde faction. without someone to occupy the cities you conquer they often quickly get resettled and you end up playing whack-a-mole. This way they can't. Also, it has interesting implications depending on how capable this vassal is.
Also, I really like that we get some kroxigors. The Original ones were kind of terrible, so if these work that'd be nice.
And I'm curious how the razordons will play. We have quite a lot of shooting all of a sudden with razordons & salamanders appearing.
The human faction looks interesting as well. Having to balance the wrath of the lizards with getting the approval of the emporer.
