Heck, I wish it would just declare victory a lot earlier than it already does. As it stands now it makes you play it out well past the point where anybody has any chance of actually catching up with you.
Preach! I like religious victories because I spend the majority of the game setting up the infrastructure for the apostle spam to finish it, and that's usually less than 15 turns - Rough estimate is 90% of the game is setting up for victory and 10% activating the completion. I like Dom games because I enjoy the early game bulldozing other civs (avoiding those with coastal capitals) but then when war weariness starts to creep in it's ugly face I make peace with everyone, get two frigate/battleship armadas and one naval melee unit per capital left, put them in position, DoW everyone with a capital left and finish the game two turns later. I like cultural victories the most because not only are there soooo many avenues to generate the game-winning yield, but once I have unlocked the final tools that I'm exploiting to get the win, it's over in less than 8 turns. But Science? Snoozefests. I get to the point where I'm 3 eras ahead in science and 2 eras ahead in culture, have enough GPT to buy multiple potential game-ending units every turn, triple to quadruple the amount of cities of the second largest civilization, and there's still HOURS left to play, which I try to actually play to keep myself engaged, but it's really a matter of clicking next turn over and over again. And, for me, Diplo is by far the worst. I've set out 5 times to try to get a DV, and only completed it once, not because I lose the game, but because the game is clearly decided but I have only 13 out of 20 points needed (I get everything on the checklist - the 3 wonders, the tech and the civic, voted for the winning decision in the first two elections) so I gotta play at least 60 more turns after the game is decided and another reason I'll get to in a minute. And while I pray to the civ gods for it, I've never seen an Aid Request mission before I start ticking off the planet with coal plants, and even after that I've only seen 2 in the last 9 games combined. The one time I actually got a diplomatic victory, I got about 20 future techs and future civics each, could have built a spaceship two voting eras ago, at any point could buy a world-conquering military in less than 5 turns, and would have won a culture victory if it wasn't turned off half the game ago
I DO min/max and have no shame in admitting it; because I HAVE TO. My machine sucks, and even playing on small maps exclusively, once turn 170ish rolls around, I start seeing performance issues. At turn 200, it runs really slow and Heaven forbid I call it a night and have to load a save the next day, what I do is to load the game up before I go on my morning walk/jog, and then load the save file before I get in the shower, and it's still loading after I finish showering. At turn 230, I can't play anymore because the game will freeze and crash every third turn. As such, I need to lock in a victory and soon, so here's how my last 9 games finished (all immortal or Deity except 2 Emperor games):
-Gitarja: Science victory: turn 187
-Peter: Culture victory: turn 166
-Kupe: Religious victory: turn 141
-Tomyris: Domination: turn 142
-TeddyBull: Diplomatic: turn 211
-Kristina: Science: turn 190
-Joao: Domination: turn 154
-Lady Six: Religious: turn 122
-Gorgo: Science: turn 193
So while my situation is a little unique in that my equipment forces me to prioritize winning early or fail to achieve a victory condition, I have to ask, if people are unintentionally winning Diplomatic victories, what turn are you winning on? I get that it's the "default" victory condition because you will always generate DV points every 30 turns, but to me it seems like if you win it by accident while
actively pursuing a different victory condition, then you need to work on your ability to achieve that victory condition. Apologies if that comes off as condescending; I'm not the greatest player myself by a long measure and probably fall into the bottom half of the pack of Civfanatics, but it seems to me that with the frequency that DV points come along, there's more than ample time to pop a different VC before it accidentally triggers.
