You'll get a good sense of the mechanics with the next three videos, primarily you are performing challenges that take time based on your skill with the challenge vs the defensive stat of the POI and any defending heroes. Everything feeds from that basic concept, including heroes attempting to disrupt your actions and events that spawn from the challenge based on traits and abilities.
I actually talk a bit about opening strategy in the second video, which has not yet been posted (I will be posting it tomorrow if it still doesn't go up). The most confusing part of the game for the player is that the entire map is open for you to work with - you can summon your agents into any spot on the map and set them to work. However, it also simply lets you pursue the strategy that appeals to you, ally with that nearby orc kingdom, try to overthrow a republic and plant one of your agents in control, foment war between two nations, start trade wars by encouraging guild growth, burn farmlands to create an international famine, hunt for ancient artifacts inside ancient ruins, rush to get a powerful agent and leverage his abiltiies, and of course my favorite "assassinate every king in the game" - it makes the AI so paranoid.
A little concerned that no channels are picking up the videos (except RPGWatch), so we may be putting together a trailer next week - if I post it here first you guys want to give me some feedback so I can quickly make any edits before sending it out?
No demo yet - it's probably a month out. Only The North Burns will be in the demo, the Black Seas is actually a testbed for Guilds and Naval movement/combat, which is still being fleshed out. The AI currently has some difficulties with anything outside straight military convoys, and it's easy to just move agents between ports without problems. The Black Seas will undoubtedly show up in some form, but I think it will be adjusted to match a stronger overall theme. We are working on another Scenario that involves an Empire and its colonies, but content is ahead of development at this point (due to KS planning/marketing).
