In the beginning  the concept of @Mythos_Ruler It was the one from the Grand campaign( the original), but then it was changed to the one from a more simple Grand camping from Wraitii. I never thought I'd see that original concept resurrected, and I'm eager to try it.

Not sure how to respond to that... Anyway the branch is designed to support creating campaigns with an adapted toolbox/framework (or would have the ambition to be). The campaign I created showcase the new possibilities, but my work is mostly on creating the features. And I suck at the rest. A great campaign could be much more worked out. If @Lopess , or some great moder, would want to create a campaign on it, that would make things interesting. I know there have been posts, from different people, about ongoing work on campaign map but this one has probably the best perks and it's provably already playable. On this branch I think many things can be done, for example making a dragon capable to land on a melee fight with good effects, could already be done easily but it needs the art.

The game should have multiple ways to play, not just mods or forks    By the way, this would be the second ( grand) campaign map; Lopes is working on another one.  

Yes @guerringuerrin, thanks for trying it!! The main way to recruit is to station an army in a city. There, the recruitment is faster then from making your army into a camp; and some building/city upgrades can make it even faster. For example here I'm recruiting 6 battalions (full regiment) in a single turn from a full grown city with a barrack:   Changing an army state to encamp also unlock recruitment as you found out, but it's slower. However it's very convenient forgetting back a battalion where some units might have fallen. My army have weakened battalions after a battle :   I can encamp and refill some of my battalions under a turn : But noted, I'll add a small step to the starting tips/walkthrough on how to recruit units 

Most of us are volunteers, and the truth is, there's very little gameplay discussion in recent years, no real direction. What I'm seeing is a division among those who love competitive online gaming and a historically more conservative and slower game. That it be more strategic and in decision-making.
