I dunno, what I definately don’t remember from previous Civ games is the degree of warmongering.
In most games (on Standard size maps), some AI will inevitabely conquer all others on any given continent.
So if there’s three continents, you’ll end up with three civs.
If there’s another AI civ on your own home continent, it’s pretty much inevitable that it’ll attack you at some point.
If you are isolated on a small continent and all you have is club wielding warriors in the year 2000, it’ll mostly matter little, as the AIs lust for conquest often stops when it has conquered it’s home continent.
The closer your continent is to theirs, the higher the risk they’ll eventually attack you regardless, but chances are the game is over by then.
Late game modern wars are often blitzkriegs, the AI is completely unable to defend itself even against other AIs and gets overrun in little time.
The AI leaders then conquer (often puppet) everything and end up with huge holdings.
Fighting these consolidated continents is often like stirring up a hornets nest, but due to limited AI doable even with a much smaller army.
So the military game is pretty fun.
The science victory can also be fun, because it’s essentially the builders victory - you’ll need a at least mid-sized properly balanced and well developed empire to pull it off, and it’s not neccessary to fully commit to it from early on, so your armies can see some action etc.
The cultural victory is very dull - unless you want to minmax is and deal with puppets and stuff, it’s best to have only one to three cities and buff them up with the tons of cultural buildings. Getting the relevant wonders helps a bunch, but with a very small empire emphasing culture it’s a doable victory condition - just very dull. You cannot really afford to get sidetracked too much.
Also, I alsways liked the exploration aspect of Civ the most, and in Civ5 it’s over all too soon. Once most lands have been settled, there’s absolutely nothing you can do in enemy lands. There’s not even exploration with a non-combat unit like the Diplomat in Civ1 or manual trading with caravans.
And there’s no cultural-strength that can push your borders without engaging in combat (and don’t mention that crap culture bomb ability).
The AI almost never offers actual trades, only open border agreements, secrecy and cooperation pacts. There’s no tech trading, either, nor are there options for other nuanced diplomatic deals of whatever kind.
So it’s either warfare or city building where the actual building takes a very long time and is running on slow turns which means pressing next turn, waiting a minute, pressing next turn, waiting another minute … you get the point.
This stuff needs some spice.
