I'm not here to resurrect the old "this game was trash on release" v "this game has been boffo from the start" debate. Personally, having played EU, EU2, EU3 (which I stopped playing after three attempts at starting it produced no desire to continue) and EU4, I will say that this game was not as good "out of the box" as 1, definitely not as good as 2, but better than 3 (by "good", btw, I don't mean bug issues, I mean design). I will also say this: that if the game didn't have a random Western Hemisphere generator, I'd have played it once (my usual Portugal test game), and stopped playing it thereafter. It was not (prior to the DLC releases) particularly a good game, in my opinion (and I've played computer games since, oh, discounting "Pong", roughly 1978, on mainframe, mini-, micro-, laptop, phone, pad, watch, etc., so I have at least an informed opinion, for what it is worth).
I will also say that, my one MP experience with this game, had I not known that there were changes coming, would have been sufficient to put me off playing it MP, absent some of what I see coming in AoW. This nonsense of having click-fests without pauses, while trying to re-build armies and fleets is absurd. AND, it was absurd ab initio, and the solution is so obvious, that to have not addressed it from early on alpha testing is, IMHO, inexcusable.
Which is why I made my statement (which you mis-characterize, btw). My statement is that many of the changes/fixes in AoW, combined with the original game, would have made a very good original game. THEN, they could have released CoP (preferably getting it, you know, correct when they did), followed by WoN, etc. And had they gone about it that way, the original release, offered anywhere from 6 to 9 months later, would have been quite excellent.
Take the expanded maps, for example. The map for Western Europe in EU4 has been much more detailed than the EU2 or EU3 maps. This means they are committed to the concept of more detail in their maps. Do you really believe that, with this idea in mind, they needed the community's input and inspiration to come up with detailed maps of Asia, Africa and the Americas? If so, you need to stop drinking the Kool-Aid.
I refuse to accept the new-fangled notion that the best way under streaming dissemination to satisfy your fan base is to offer to market handicapped versions of what you want a game to be, then hammer out fixes and offer prosthetics while finishing your original design over time, along with "oh, by the way, do you have another $25 to spend now?" DLC. If that's going to be the model, they might as well just go the whole hog and have us pay a monthly subscription, then stream out new content as their hearts desire, without bothering to call it DLC, or expansion, or any other such silly words.
