There are certainly differences in the individual countries' chances to win. I think France is the easiest, England next, Prussia and Austria next. The otehrs behind. That's from my experience, others may disagree. I have migrated towards those countries that have a harder time winning (Russia/Turkey/Spain) just for the challenge, but I learned the game playing France and Britain.
So, maybe you shoud try the same thing. Spain is in a VERY difficult position and has to get a little lucky to have much of a chance. Generally, if she goes to war with France, even one time, she's in real trouble, because France can crush the poor Spaniards like no other country can. But, Spain is fun to play, in any case. Go with the long games (23 years, Highest Glory). I've had better luck with those.
