The meta here is ridiculous. You're calling me out for use of an "ad hominem" instead of a serious argued response, when you haven't made a serious argument either and have responded to two of my posts with snarky/sarcastic personal attacks as well.
I don't have a problem with an ad-hominem (a stupid argument is the result of stupidity or insincerity, after all), but you can't engage in the same unless you get off your high horse.
Since you so desire though, I'll respond seriously:
We're all okay with Poland getting nuclear weaponry at Tech 28, right? I mean, after all, none of us have the necessary historical understanding to say it couldn't have happened, right?
I'm not sure how you got this from my post; the absurdity of somehow drawing that conclusion is what actually made me consider the possibility of your post being a parody of some members of the forum (especially the oft used "Why not give X nukes/tanks/bombers").
The poster I responded to said that for immersive purposes, Tuscany (Firenze) dominating Italy is less jarring than a modernized, colonizing berber state. This implies that he believes that the odds of the Tuscany scenario are better than the Berber scenario, though he hasn't explained why. I've studied firenze fairly extensively, and couldn't imagine them actually dominating the region. The government had difficulties collecting sufficient tax revenue throughout the period in peacetime and even small expeditions devastated their public finances for decades. The Berbers, on the other hand, I know little about, so to my knowledge that scenario is anywhere from impossible to probable, so the result doesn't test my immersion.
The point of course being that your immersion is relative to your knowledge base, with things you're well knowledgeable about (or woefully ill-informed about) often straining it.
Re-reading my point at the end, you're right, I expressed myself quite terribly. In my defense, I'm still quite peeved about a number of changes, which are quite unrealistic/immersion-breaking, yet PI did anyway (colonization, hordes, etc.), stating that they were necessary for gameplay/balance purposes.
At the end of the day, this isn't even a game about immersion, and isn't really intended to be. Developer statements and many design decisions make that abundantly clear
What I should have written is that the primary focus of the game isn't immersion. Immersion does, obviously, play an important role. However, that doesn't mean it's the foremost driver of design changes. Awhile back, Johan stated the design goal was to be a competitive game, and this has played out through the updates. If you read through the dev diaries and patch information, this distinction is quite clear. Some changes are made for realism/immersion, but most are made with the intent of enhancing gameplay experience or improving competitive balance (not always successfully), often at the expense of realism/immersion.
An easy example of this is the change to colonized provinces. It's quite unrealistic/immersion-breaking that a Colonial Nation would be vastly more efficient in colonized territory than a same-continent native or that an uncolonized province right next to a Russian province with no LA floor will have a 50% floor when Russia colonized it. In spite of this, the change was made for competitive balance purposes (Asian countries could reap more from Asian colonies than Europeans quicker, full income with capital move to America, etc.)
So if someone has an issue with something being immersion breaking and desires design change, it's far more effective to argue from a gameplay perspective. If something would be more immersive but hurt gameplay/balance, good luck getting it implemented.
