Haha. I rag on Paradox every chance I get and I've been playing their games since the day EU1 came out. If there ever was a money grubbing whore of a tease company, it is Paradox.
All of the EU games are essentially the same with graphical improvements or some tweaks to how you pay for crap. It isn't like they've greatly expanded any facet of the game. Its still essentially the same damn game I've been playing since I was a teenager. And yes, I am 30. Same with Hearts of Iron, although in that series they've at least tried to get semi-close to the intricacies of HOI1 with HOI3, but still, not near as much.
I buy their games, because that's just what I do. Same as CA games. Doesn't mean I won't rag all over a terrible product, and Paradox has made some terrible products. None of which I can forgive simply because "they've had a good run since CKII" (I've read this argument on this forum before). A decade of buggy, broken crap doesn't just remove itself from my memory.
But hey, I'm still playing! Meh, I hate them, and I think their games are pretty meh overall, but they make a unique product that suites me so I gladly fork over my cash for basically everything they've ever made.
