1) That Aruolo castle scene looks epic - keep it going.
*disclosure: i know this is a little bit of a rant, but please correct me if i've misinterpreted some information and am making an idiot of myself
i'll take it all back*
2) "The player will be able to hire a continent of household troops from the constable. It will cost 30000 aurums each troop. However, these have the capacity to become the best troops in the game, as you can very easily change their equipment to any of the armors and weapons in Perisno."
UHHHHHHHH!? Where to start....

-> "continent"...i presume you mean contingent right? (v. small point in the grand scale of things i'll admit

)
-> 30,000 EACH TROOP?! I don't think i'd consider even recruiting 1 if it works how i understand it to. So you hire a troop, then you've got to buy it all the super-expensive armor so it won't die, and the weapons and the horses...that is already at ~70k+ if you want them to be better than Eagle Retainers who are VERY easy to get.
(i'm going to ignore what level they start at and how their stats work because i don't want to make presumptions)
So considering you can quite easily recruit dozens of Eagle Knights/Demon Priests who have exceptional stats and armor, i don't think these units would be vaguely viable in terms of cost.
A) capture some pilgrims, level them up through Retainer (where they're already v. good) to Eagle Knights for a few hundred...voila
B) Spend ~50,000g (low-end cost) to create a single troop whose armor values won't even be that much higher.
*disclosure: i know this is a little bit of a rant, but please correct me if i've misinterpreted some information and am making an idiot of myself
i'll take it all back*
But apart from that little rant *sorry*, this is a great idea and i love having the chance to create/possess slightly "different" troops (like the Order system in PoP was one of my favourite ever M&B things)
Thanks and keep it going.
