In my opinion your list would not make a good game. Only micromanagement hell...
Sure it wouldn't make a good game, as those are only ideas I spent a few seconds on. If I were developing a new game, I'd think of something more consistent. Still, I think the mix of two settings is essential. Game complex enought for people to acknowledge it as realistic, with ability to micromanage if needed is one. Second is a system that would make AI manage all the details, so that player is forced to plan, not to introduce strategy. He don't have to be genius to manage the empire.... Still, he has to be brilliant in order to make his empire flourish.
He would have to be able to observe how his strategy works on a low level... And there should be no easy paths of how to be succesfull, as situation should dynamically change. Of course, this is only a perfect model in an imperfect world of weak computers, programmers working on food, having families and people fearing the risk.
Besides, EU3 *is* the new engine!
As the topic states, we are discussing about EU4, not EU3. If I had to write about improvements in EU3, I'd have written completely different post.
A game this complex and with this subject matter will always catter only to a narrow community.
I think you're wrong. The series of Civilization, Colonization, and a few other games were adressing very similar subject, and gained much more interrest. If history is well wrapped, it can be sold very succesfully. Without destroying the original historic flavour. It's all the matter of balance, and usually a bit of passion.
EU3 "diplomacy" is just for sissies...
Did you ever even try to play MP EU? From your attitude I can see what could have turned you off from it. When I want to play with body language, I play poker with friends. When I want a diplomacy, where I have to deal with all kinds of people, in a different , unpredictable situations, to feel them from the beginning, I prefer EU.
Of course, everyone can have what he likes, and that's great. Still, I don't think Magna Mundi is EU4. It's a great mod, I even spent time on beta-testing it and my name is (or was) in instruction... Still, it's not for me. It's only conversion, whereas I'd like to see something that would make people astonished just as they were when first version of EU hit the market.
Well, if Paradox won't make such a game, in the future someone shurely will. Then cutting coupons from EU1 can end.
