Damn you for posting this without providing a demo!
I really like the concept, although I'm not 100 sold on the ADM points. I didn't like the way it was implemented in EUIV, and I'm afraid it'll feel a bit of an artificial limit. Although it'll depend a lot on the implementation, I like the idea of sectors, governors etc etc having their own ADM points needed to implement your edicts.
Another question, how fast will the game be? Let's say you're quite successful and live to 80, how long in terms of hours of play would that be?
Well, Imperia does ADM a lot different than in EUIV. There will be a natural progression as you age and get more adept at leadership. I think you'll really like the macromanagement that the system provides - for example, instead of designing a colony ship, building the ship, staffing the ship, sending it to a planet (possibly with a protection fleet), and having it colonize a planet, from then you have to babysit as you build the 'standard' opening stuff, you can just create an Edict on a planet you want to colonize, assign the ADM, and.... wait for it to be done!
As for how fast, turns can go pretty quickly once you've figured out what you have to do. I'd say the first few turns could take a while, since you have to assess your empire, your trade network, what planets are in more dire straits than others, and learn your people, but after that they go quick. I'll say I've only played 50 turns (5 years) as the longest game and that took me about 2 hours, so extrapolate from there. Also, there will be many more strategic options as I add to the game.
