And then after seeing some of the older versions of EU posted in this thread I am also a little sad because EUIV is looking like every other strategy map, we have entered the Ikea era of the flat pack strategy map.
If there exists a best way of dividing up the map for a given number of provinces, then there is no wonder it will be found sooner or later. We may never know if there is such a best way, but going along natural borders is as good an idea as possible. So I think there is no wonder in strategy games getting more and more similar maps.
It would be nice, and also solve some problems with oddly-shaped provinces, if Paradox let armies roam freely constrained only by terrain like in real time strategies. Definitely not saying I want the game to be like a typical real time strategy, just that the current system with connections and travel times and armies warping between province centers after travel times elapse is rather clunky and prevents Paradox from ever really doing anything fun with on-map tactics.
Hey, if Paradox is going to spend a bunch of time painting the map with elevation and trees etc., why not use that information for a more free-form movement, terrain, and combat system?
Maybe in EU V.

Not that I am against this idea, but it would allow too much freedom for army movement. As in, the AI couldn't hope to cope with the task, while human player-generals easily can. Which would turn the game into something much akin to TW: domination of the world not by strategy, diplomacy and micromanagement, but through tactical prowess.
On the other hand, personally I won't take using HoI3's map (provinces) as an insult.
While I must say that all this eyecandy is appeasing, the main role of the map is to convey information. That's why I praised EU3 in relation to other games - it was a game for the brain,
a game where strategy was really set above looks. That is why I love Paradox' titles.
I don't mind looks, just I don't play these games for the looks.
Also I often find myself clicking back and forth between two tabs when trying to choose a major course of action. Could this chore possibly be alleviated by allowing us to have two separate tabs open beside each other?
