There is nothing special about that. Look anywhere in the world and you will see countless of wars among neighbours throughout history.
I think denmark have had atleast 10 wars with sweden sofar, as one example.
hmm or maybe:
UB: Starcraft Playhall: Replaces Stadium. Gives a extra 2 happiness.
Well, Denmark, Sweden and Norway all used to be part of the Viking kingdom, Denmark. When Sweden wanted to part ways, they fought, unfortunately for Denmark, Sweden was better in the end and we get to see how Gustavus Adolphus changed renaissance warfare, and how little Sweden managed to war and even won against Moscovite and various German principalities.
Every relationship in the world is unique and complex. Still, I feel pretty safe in saying that most European cultural tensions aren't quite as intense as East Asia's currently are.
The modern atmosphere of Europe, and Denmark and Sweden as you mentioned, is very far removed from the sort of thing I'm referring to in East Asia.
I think one reason is for most of Europe's history, it's feudal monarchy and the European royal houses tend to marry into each other so in the end, essentially the entire European monarchy are all relatives. Asia does not do that in that regard, it's more conquest and/or culture satelites. India was strong under the Gupta dynasty but most of the time, India gained cultural influence with its religion, influenced China which in turn influenced Japan & Korea and spread to Indonesia (until Islam replaced buddism in that region). Asia had 2 super power houses that dominated most of its history, China & India. Japan gained power & influence in the last 100 years but it was mostly China & India's show for the past 2000 or so years in Asia. Smaller nations in that area either become a culture satellite of either one of those 2 civilization or they might be gone. Khmer and Siam had strong Indian influence. China essentially seeped into Burma and controlled Indo-China area for a long time (around Han dynasty if I recall, which is about Roman time).
There's fear and some of it is justified. Europeans fought many long bloody wars where entire population was decimated. 30 years war in Germany killed off probably 1/4 to 1/3 of the population, if not more. Spanish Inquisition was not very kind either. People in Europe have learned to live with each other better, at least that's the impression I got when I studied in Europe and talked to Europeans there and here.
Another thing is Europe is more fluid in terms of influence + power. The Celts, Vikings, Romans, Germanic tribes, the Franks, Hungarian, Poland, Lithuanian, Sweden, Italian, Spaniards, Greeks, Russians, England/UK, Austria-Hungary empire (Hapsburgs), even Holland/Flanders had its own influential times. This is in contrast to Asia where it's mostly evolving around the 2 super power, China & India for the past 2000 years.
Right, I also have started to prefer smaller maps. I don't know how slow it gets for you though and what system you have. The thing is that for me strategic view crashes game after like a minute, so I started to look for solution on web and I found several people complaining about this, apparently there is some issue with frame rates on strategic map. The only solution though was to turn on VSync, which was allready on for me. Also there may be diffrence between DirectX 9 and 10/11, but for me it only fixed issue with how FoW is rendered (i.e. I had black box instead of fog at first)
Now just to stay on topic - I don't think a civilization has to conquare/colonize whole world to be worthy. However some expansion outside their national borders/domination over neighbours or at least scientific or cultural advancement should occur. So I see nothing wrong with having Mezoamerican civs just because they were wiped out by Europeans, when they had very rich culture, fairly well developed science and complex social structure well before European contact. I never ever have heard Korea having large teritory or making notable contributions to world culture or technology. My country has very Euro-centric history education, though. However I would still prefer learning more about Africa and other great civilizations world hasn't heard of rather than modern day Asian countries
When I use normal view on maps bigger than small, I get black areas then slowly turned to gray and other landscape color and you can see the graphics being rendered. My CPU is slower by I think about 0.2 or 0.4 Ghz below the minimum requirement and my graphics card may not be late enough generation. I have enough video memory on my video card (512MB) and enough memory (4GB but only runs on 32-bit Windows so only 3.5GB is used).
