By that logic, Starcraft is only good for 3 playthroughs. How do you expect people to play chess for the 1000th time if they haven't added any new pieces in centuries.
Replayability lies not just in trying something different. It's also in the mastery and in trying the familiar in a new environment. Check the statistics for EU4 - people do net keep trying new nations every game, they keep coming back to the big ones, time and time again. Where do they find the replayability if it can only be found in something completely different, I wonder.
But even if we agree to write off 75% of all replayability, that still matters little. The real replayability killer is the ability to change your ethics in-game, because it means you can try all the ethics, sans Hive Mind, in a single playthrough, albeit a long one. Same goes for civics and government in general. Basically, the game has been reduced to 3 ascention patchs (as those are mutually exclusive, HIve Minds and those fixed civics (Machinist, Convergent Evolution). Everything else can be tested in a single playtrough.
And why would you care for people to play a 1000 times anyway? Whichever fanatic does that is clearly not concerned with replayability as defined by you anyway. What concerns the devs is a player who plays enough to keep coming back when a new DLC is released, or a new iteration of the game. And as each DLC and iteration changes the replayability, the only concern is giving people enough content to play enough games in between those, to be interested in having more. Which isn't even 50 games for most players, much less 1000.
I like playing Orthodox countries, in EU 4, because of the stability discount and among other reasons. Due to 1444 game start date, there is not lot of variety. I do come back to them from time to time. But lately I got really bored with them. I want a change for once so I went and did Empire Strike Back achievement for fun.
I do like vareity. It doesn't meant that I play "everything once" and be done with it. No far from it.
The kind of variety I would have liked to see more of would be like playing a tall vs wide trading empire. There is so many possible way to do this. I will probability never get tried of "republic" anything. Ibadi merchant trading republic? Lets have fun! American Natives tall trading merchant republic? Sure why not!
Does it have to be powerful? Naw just a different way of something. Right now Hive Mind Govt only real choices that make them different from other Hive Mind is fairly limited to a select few items and most of those are ALREADY used by other non-Hive Mind. Think species portrait, flag color/symbols, starting FTL/weapon type, civic choices, and ascension peak.
Civic choices and Ascension Peak is the only things that would mark an unique set of playing styles at least when it comes to unique Hive Mind features. On the other hand non-Hive Mind has FAR more diversity going on that you can't really play the "same" game twice.
For example, Suppose if you want to start as a fanatic Xenophobe and start up a new game. You start right next to a fallen xenophile empire. So in 1.5 you are forced to give up "purge everything" stance and go bit softer. In another game you have 15 "great" solar system next door to your home system and nobody can fight you in the end.
IE for Hive Mind diversity play style examples; going for full tall, space habitation and superstructure, with full biological ascension. Or gain "Defender of the Galaxy" and wide game play ascension peaks while avoiding biological ascension peaks.
There is only so many combination, between ascension peak and civic picks, you can try before you got bored. I am asking for more variety in few ways. Make it possible to go full PSI ascension Hive Mind or Cybernetic Hive Mind would help mitigation this issue.
I was hoping that Hive Mind civic choices would be more different than non-Hive Mind civic. What I have seen so thus far is disappoint on score of diversity.
idk...judging by the description hivemind offers stability and control over your empire. if it's true then for me the answer to your question will be "with great pleasure"
Erm... Sure I guess.
I may get so bored enough to actually get into mod making to change up around bit more personally.
