I think this is an excellent and important way to classify because in many respects, as you pointed out, the shit's different. (though Kamakai may point out that Greece is never considered CE anywhere
EE = generally poorer, more "Eastern", more gritty, worse infrastructure, frequent scams, more gold-digging, more stressful. And hence, more appropriate for those who are adventure types, especially who don't suffer fools gladly, and don't know what oneitis means
My faves (for the types of women I like) Russia (tall, sweet, blue-eyed) and Romania (sexy, promiscuous, Latin types). (*never been to Baltics.)
CS = generally better off, more "European", less gritty, better infrastructure, rare to few scams, less gold-digging, more relaxed. And hence, more appropriate for those who are looking to marry better stock (though it may be harder). My faves (for the types of women I like) Slovakia (beautiful, traditional, family oriented, age well, even in their 30s and 40s look great), Hungary (some nice looking women there, they also keep fit and age well), Serbia (perhaps most difficult on the list, unless you are Italian, Spanish, or Greek, in that order. Then it's much easier. Great women when young, but aging worse then Czechs, Slovaks and Hungarians, also smoke a lot, so buyer beware.)
My favorite playing grounds in Europe:
Draw an imaginary straight line starting from Gdansk, Poland and go all the way down until you run out of land. Follow that line, with a leeway of about 200 or so km on either left or right side of that line, and you're good to go.
Best months to play: April, May, June, September - with June being the best because it's sunny and dry, but not too warm (April could still be cold, May could be rainy) and everyone's still in town (people are heading on vacations in July and August), and women are abundant and half naked and pheromones and gina tingles are in the air. Day game paradise.
