As you have all pointed out, Civ 4 had a lot of flaws. Tech trading is one of them. Firaxis did away with tech trading, that's great. Civ 4 also did some things spectacularly well - the maintenance system. Civ 4's maintenance was far superior to the global happiness of Civ 5, or the nonexistant empire expansion limit in Civ 6.
But perhaps the problem here is just that Firaxis no longer makes the kind of game I want to play, and that's personal. The AI could catch me with my pants down in Civ 4. If I sat there wonderspamming and barely building an army, and the AI sat there building up an army of axemen/swordmen, then came a knockin, I was done for. In Civ 5 this just ceased to be a problem. I could build a bare minimum of troops and fend off an invasion from just about anything, due to 1 UPT and strong defender advantage.
I suppose this is where I differ from most players. If I only built 2 warriors and 2 archers, and the AI declares a surprise war and comes at me with 4 spearmen, 4 warriors, 6 archers, and 2 catapults, I think I should be dead. But in Civ 6 I don't even sweat, I just shrug and think "oh, okay, I have to delay whatever it is I was doing for about 5-10 turns". I'm not worried at all. I'm basically invincible and never need to worry about losing a city. Ever. And if the AI manages to beat me to a wonder, in the back of my mind I know I can just march an army of 2 knights and 2 crossbowmen and take that city, no problem.
This was also the case in Civ 5, though it wasn't quite as bad. I think of Civ 6 as playing Farmville or the Sims. I could sit here arguing with my girlfriend about the fact that the Rachel character in Friends had no desirable qualities beyond attractiveness, while keeping an eye on the pasta on the stove, and casually clicking buttons and win a Civ 6 game on deity. Hell, my gf could probably do it. Victory is inevitable.
Civ 4 was not like this at all. When that horn sounded and that AI stack of doom crossed the border onto my land, I can tell you my palms were sweaty and my heart was pounding my chest like the fists of a heavyweight boxer. Games were nail-biters.
Look, there's nothing wrong with playing The Sims, or Sim City. I play those games, occasionally. They're entertaining in their own way. But to me, Civ is supposed to be different. When I play board games with my friends, like Risk, or hell, even a game of chess, I have no idea if I will win. The fun comes from knowing that I need to do my best to actually affect the game's outcome, and that others are doing their best to beat me. Civ 4 gave me that feeling. Civ 5 did not, but it was close.
Civ 6 is a joke. On deity, the AI barely builds a military and then doesn't bother to upgrade it. The warmonger penalties are meant to discourage being, well, a warmonger, but I quickly learned that having the entire world declare war on me was meaningless when I could take on the entire world and win. Try doing that in Civ 4. Sometimes you could fend off a 2 on 1 dogpile, for a while. Mayble. But 3 on 1? Forget it, you're done.
I said this a long time ago, before Civ 6 came out - that to me the absolute most important thing for Firaxis to do with Civ 6 was to either a) make the game a primarily multiplayer game and design it to work as such, or b) make the AI their #1 priority. They clearly did neither. I don't care how interesting the district system is (it's not), or how wonderful the graphics are (they aren't), none of it matters when the AI sits around sucking its thumb and I can just do what I like, as if I'm playing Sim City.
Stacks of Doom have always been weak programming IMHO....& I have been caught off-guard multiple times by the AI, even on lower difficulty settings in Civ6. Your claims of "no maintainance" & "infinite expansion" are a load of utter tosh. Buildings have a maintainance cost, & a mixture of Amenities, Housing & District/Wonder requirements place strong restrictions on rampant city spamming (as do the costs of settlers). I'd love to see a return of the Distance & # of City multipliers for maintainance costs, but their current absence are not ruining the game, & we certainly have not returned to the ICS days that plagued Civs 1-3.
