What I am meaning is one of the best aspects and most distinctive is the ability to have multiple units on the same tile. That is an ability that has been with Civilization from the beginning
Enh, sooort of.
In Civ1 and 2 you never really stacked units more than 2 high, at least not anywhere near the enemy. You might pair a high-defence unit with a high-attack unit, such as a musket with a cavalry. But other than that it was a pretty bad idea. While units could stack for movement purposes, for purposes of combat, there was just 1 defender, and if he got killed, the whole stack was destroyed. So in a way it was 1 upt - you just got to move in the same square (at the risk of losing the whole stack).
Civ3 was the first time you were allowed to have multiple defenders, and with that came the SOD, which we've been trying to get rid of ever since. That's why suicide catapults were introduced in civ4 - as SOD-busters, even though the idea of suicide artillery makes utterly no sense at all. Plus it didn't work since we still have SODs, they're just made of catapults now.
That isn't good tinkering with a game in such a major way, as you lose what the game is about. If they want a war simulator why couldn't they produce a separate game where you could only have one unit per tile and leave Civilization V to be more like an improved Civ IV.
If all you want is civ4, keep playing civ4 by all means! I'm sure all kinds of mods that improve on it will continue to be produced and refined. You should probably at least
try civ5 sometime though, just in case.
The point of a new edition is not to create a slightly improved version of the same old thing - that's what expansion packs are for. The whole point of a new edition is changing the game in relatively major ways.
I don't think civ will be or is aiming to be a "war simulation". Changing the quality of warfare in the game is not the same thing as changing the quantity of warfare in the game.
Also we have the fact that there are millions of posts in threads such as these by fans of this site that seem to be asking major questions on how the new system is meant to work. These are what I am pointing out.
Of course, because the game is months away from release and lots of details are still a mystery, meaning there is alot of speculation and alot of people wanting to know more details. This happens every time a new edition is released. Nobody really knew very much about civ4 until very shortly before its release other than a few broad details ("it has civics" "it has religion" "it has collateral damage") that nobody really knew anything about. Even when more details started to get released close to the time the game hit the shelves, to really get how the game worked you had to actually play it.
