hmm ... i am a bit disappointed that they are adding yet another military building. And it would be even worse if we keep only 1 queue for all 3 buildings combined (as it is now with barracks and the non-working Mercenary Camp).
Working on battle system is a plus, if they get it right .... LOL
But most interesting part of episode is the small insight to be seen about new race.
At 3:23 they show they are testing new race already, even though the chapter is very well blurred, BUT
At 3:13 above the popup you can see what looks like new farms. They look at first glance as Elves Planks, but they are different sizes and the road looks guest race specific. Also just above those it looks like plant-like workshops (you can see the tools complete sign)
Though new race will probably be 1-2 months away, since Battle plans will be released first i think.
Who knows?
