We can point out all sorts of flaws of Civ4 vanilla vs Civ5 vanilla but the issues I have is that in many areas where Civ5 made changes from Civ4, it made the game feel more gamey and abstract and artificial vs what I had from Civ4.
I pointed out BTS 3.19 flaws, not vanilla. If you don't think civ IV was gamey, you simply didn't know how to play it at a high level.
First as far as Civ5 "diplomacy" is concerned being "realistic", that's just really bizarre to say the least. There's already been many threads on this but suffice it to say that nations in real life history do not deal with each other like AI nations in Civ5. This is because IRL war is a lot more costly and has drawbacks in terms of the costs of waging war but also war weariness and also in terms of damaging and disrupting trade relations, its effect on world opinion and dealing with rebellions and such etc. Civ4 vanilla is flawed for sure but if you compare the two, it definitely feels a lot more "real" to me than nonsense Civ5 "diplomacy".
You are making yourself look very, very bad. If you're going to argue about the merits of previous games vs this one, do try to actually understand the mechanics of those games which have been DOCUMENTED ON THIS FORUM. IV's AI behaved no more realistically than any other in the series. Hell, in IV the AI didn't care if you killed people off one after the other as long as they didn't like them actively. In V, they care, so you're already behind. You lose trade relations/etc in both games.
Civ BTS 3.19 still has AIs that implode, don't try, and act 100% on dice rolls without any attempt to win at all outside of a culturemonger or two. You don't think PERMANENTLY locking the AI out of war is "gamey", but that some tricks in V are? That gifting nukes to both sides as a neutral nation with NO PENALTY is fine? Really? Are you REALLY going to try to go this route? How can you possibly expect us to believe you know what you're talking about when you ignore points like that?
If Civ5 diplomacy is true, the the US should be marching on Canada and conquering it right now as it is weak Civ compared to the US.
Can the BS arguments. Half the civs or more in IV would be marching all over canada. There are limitations of reality in-game.
As for other examples, take "global happiness" mechanic vs the Civ4 mechanics. As already pointed out, it just doesn't makes sense as something called happiness based on its overall effects and only makes sense if you just give up and consider it an abstract game mechanics and call it "Shafer Rating".
Oh, you mean like that GLOBAL science and gold slider, which were DEPENDENT on each other? Or that...ahem...CULTURE slider which also had a global impact on happiness? Not all mechanics make real sense, the are there for balance, and you've gone far away from "immersive" as a topic focus in your fail arguments, BTW.
I could go on and on. Yes Civ4 is far from realistic or totally historical immersive. But Civ5's changes for me and others make feel even less so. And comparing Civ5 to highly immersive mods like RoM/AND, it is no comparison at all.
So basically your argument for civ V being less immersive than other titles in the series is that:
1. You don't understand the mechanics in any of them (which you have clearly demonstrated) and happen to like the not-understood mechanics for V least.
2. You like to know that an AI you meet will do exactly the same thing every time because that is "immersive" and somehow "more realistic"
3. None of the games are realistic so that makes earlier ones more immersive
4. You are fine with some nonsense global mechanics, but not others.
5. You like mods done by competent people, who have not yet had time to make them for a newly released game.
I'm afraid that you're not standing on solid grounds, as far as arguments go.
"Immersion" is often equated with "lots of stuff", and by most metrics there is less "stuff" in 5 than in 4 BTS...
Quantity is easier to measure than quality, after all.
Are you going to give us an unbiased line-item analysis of the two releases, or are you just making something up to blow hot air?
Look, I know a LOT of things suck about civ V, but that doesn't mean people get to ignore previous flaws or make up flaws that detract from the real issue without being called on it.
