Picked up Old World when it was on sale for $4. I like adding the Crusader King Nobility to a civ style empire construction.(I could never get into CK because of its map game status.) However I found it extremely shallow, once I get to a certain point the city development is very dull and repetitive. Not as bad as Humankind's meta of your city being two halfs each the same tile improvement, but after I have my initial setting done, it seems to become a war and family management sim.
Civ 7 I find to still be much more engaging.
Civ IV is awesome. The full compliment of expansions is the most complete version if Civ. As for mods, Caveman 2 Cosmos is one of the most hopelessly autistic mods ever. It's great!
As for Civ VII... did they fix it yet?
It's definitely better. The issue with Civ 7 wasn't that it was broken. It just wasn't finished, they charged $70 for a game that should of been labeled early access. Nothing was play tested beyond it being functional, the UI was obviously not even looked at closely before release, the AI was worse than usual, clearly Cultures were cut and made into DLC. I have my suspicions that was 2k pushing for income after Midnight Suns flopped(great game though) and they were scared after Borderlands movie bombed and they had already sunk a ton of money into 4.
We just got the 1.2.5 update, and the game is in a much better place. Now that I've finally gotten around to finishing a full playthrough(more due to friends flaking off than the game itself) I have a greater appreciation to some of the elements.
Military Victory is better than it's ever been in the franchise history. Having to hunt down everyone's capital around the world has always been too tedious for me. In 7 you only need to take other settlements in Antiquity, New World ones with your religion in Exploration, and if other ideologies in Modern. To win in Modern you have to get the point victory from conquering and then develop the Hydrogen Bomb.
The legacy path system is unfinished, line everything in Civ 7, but I think it's a good fresh idea, like half to most of the new stuff in the game. The ages don't bother me as games tended to run in a few play sessions anyways, and I like the buffs you get rewarded with for doing well on legacies in the previous age.
There's a lot of other minor things, like combing civilization and city state into a shared and limited Influence resource, that I think have potential but are so half baked still that it's not worth going into detail yet.
Oof, Firaxis has been pretty pozzer with their choices, but that's even worse than Harriett Tubman(who ironically in game constantly tries to steal your technologies instead of researching them herself). At least most people have heard of Tubman.
Fun thing to do, read Firaxis' summary of Female leaders and then their actual history. Even on Wikipedia if you have a little bit of critical thinking you can see through what they say that did and the actual historical events. For example they gave Tubman a Militaristic Role because she "Lead an armed assault that freed a group of slaves from the Confederacy" and even Wikipedia states she wasn't at all involved with the assault, planning, or leadership and just snuck in before hand to speak to the slaves because she was the only one that spoke their Creole.
