Nice screenshot! I just finished my first grand campaign game of EU3: In Nomine today (1399-1821), took Mecklenburg from a two province minor in the Hanseatic League into a powerhouse Germany that directly controlled all of the area of today's Germany, most of northern Italy, all of modern Benelux, half of the Balkans, and had vassal states for all of Scandanavia. Serious fun to be had, especially dismantling the Holy Roman Empire.
All of the Paradox strategy games are made in Sweden, not in the Czech Republic. Bohemia Interactive (makers of Operation Shot in the Face and Arma: Armed Assault, the latter of which is supposedly really good after like over ten patches). So not so spreadsheety there. If we're willing to jump a bit to the Southeast we can mention Ubisoft Romania's Silent Hunter games, which are to my knowledge the only games out there where you can kick your opponent's ass with hardcore trigonometry. Boner-rific!
