I liked EU2, and I don't think EU3 is a worthy successor (although it is a good enough game in it's own right)
That said, that is water under the bridge. All I can do is hope that EU4 is a better game (I think they also need a slightly longer development-cycle.... WHile the game is a far sight better than EU2 it still has major problems and is in need of improvements (AUTOSEND MERCHANTS! WHYYYY!!!????))
If Paradox is going to have a probabilistic (It's not "Historical" as it doesen't follow history, not "Conditional" as in most cases there is an element of randomness and not just a matter of fulfilling certain criteria, it is not "Random" because there are conditions to meet to get certain results....) events-system there's still a lot of improvements: Cultural or even nation-specific events for instance (Right now nations "feel" to similar, I've been playing 200 years as England and *there is nothing that makes me feel that I'm playing England* and not say... France, or China) Events for breaking down overstretched empires (if they exist they don't seem to work: Malacca owns all of South-East asia for me. They're HUGE) AI that actually tries to gang up on a nation that becomes too strong (and most importantly, that is willing to ask for "Release nation"... If France Inherits Spain the ROTW should be buggering them to release Spain posthaste)
Also, what buggers me the most is the fact that Paradox *Didn't let us mod the game*. A simple "Create Monarch with stats of X and lifespan of Y" would have worked. Same thing with generals. It almost seems like Paradox made a defcision that "OUR WAY IS THE ONLY WAY THE GAME SHOULD BE PLAYED! MWHAHAHA!!!"
Okay, not quite, but almost.
These two commands would solve 70% of all the gripes I have with the game. (The rest are stuff for patching and such, and Autosend merchants... That one was just plain bizarre)
