Hmmm, sorry but your edit still doesn't help me much. Technically a game like the Endless War (btw link is dead) are impossible in CIV as well, but you don't seem to mind that game.
Global happiness is still around, working just like pre-G+K. If you don't like it, the XP won't change your mind. With the current AI I wouldn't imagine it being possible here either.
they have no big effects on your gameworld/history/empire like in previous games.
They scream in your face "I am a game rule, use me to win this game".
I don't get this, what do you mean? Negative happiness brings you some pretty ugly negatives, like no growth and combat penalties. Seems like a big effect on me.
The immersion of leading a nation through the tides of history is gone. now its just about using certain mechanics to reach a victory condition.
This isn't helping at all, you are just repeating yourself.
What don't you like about the systems in V, be
concrete. The victory conditions haven't changed that much since 4. The Diplo VC has been changed, now no civ can vote for itself.
You can name units and cities, I dunno, that's enough for me. The expansion doesn't bring back the option to rename your civ though.
so, i hoped that at last with religions there is maybe a small step into that direction...
but if no other steps are taken to open up the paths of this game....hmm..
What paths, be more precise about this.
From my perspective the expansion brings some needed customizability and immersion back. Civs don't hate you for "winning the game", stupid immersion breaking feature, and City States don't feel like money sinkers the way they did before. The technology tree has been revised for the better, it's possible now to be friends with civs and it seems they aren't pursuing a VC as actively as before, which also helps. But with your extremely vague comments about "streamlined game-mechanisms" (which exactly?) and "paths" I just don't quite understand what you are looking for.
CIV for me already wasn't much of a "simulation" (love the game, just sayin') by getting rid of the palace/throne room, and focusing the game more on the leaders and not the nations - I don't have the Aztec for a neighbour, I have Monty. I have Open Borders with someone, I DOW him and all my units get magically transported aback to the border. Which btw is indicated with bright and shiny colours. So I've never
quite played a Civ game as a simulation in close to a decade.
