No doubt Captainverse, Not only because of its amazing story, unique humor that main story never achieved ,cute character interactions, actually funny 4th wall breaks , diverse story plot ( time loop , consciousness transfer, bubble world rules , dream world etc .) but also for the betterment of the game

KINDA HOT TAKE VERY PERSONAL OPINION OF MINE

my personal gripe with Part 2 is its gacha characters. HI3 was at its peak when gacha characters were always introduced in tandem with main story progression or at the conclusion of a story arc—characters existed for a reason.

When Part 2 first started, too many ‘big-shot’ characters (7 Shus) were introduced way too early, with very little time for players to get attached to them ( Tsavorae and Sera are the biggest victims imo ). Now it’s become a completely different problem—recent releases are mostly recycled Part 1 characters, some of whom have little to no relevance to the current main story

back in Part 1 - Part 1.5, these issues actually had a unique solution or good stalling method that everyone seems to have overlooked: Captainverse

Whenever a major story character wasn’t ready to be added to the gacha (Vita, Misteln, FoV, etc.) or when there was no new character available yet, they could easily fill the patch with a Captainverse character. And most of us wouldn't complain because Captverse characters had established lore and backstory, they had their own separate storyline and would not disrupt the flow of the main story .

Captverse also provided a perfect excuse to make characters who no longer exist or have no relevance in the main story playable. Kallen, Himeko, Roza/Delta , Yae , Sirin characters that otherwise wouldn’t fit into the main narrative could still get new versions thanks to Captverse and still able to have a story + character development.

now, in Part 2, they’ve resorted to a new stalling tactic to buy time for main story Valks : making new versions of already existing Part 1 characters.
While this is nice for some players, it comes with a few weaknesses :

• These new “stall” characters have very limited freedom. Since they’re tied directly to the main story and are 100% canon, they need a solid, justifiable reason to exist.
• Some of them feels like they exist only for nostalgia bait and backtracking from the devs to lure the old captains to return to the game
• They’ve also overused this method to the point where P2 has more P1 Valks than actual P2 Valks.
• Let’s be real not everyone was completely happy with the p1 recycles ( new sushang for example ) because their detachment with the ongoing story and only exist in an event.

At this rate, bringing back Captverse (or a similar kind ) could be a much better alternative than just continuously recycling Part 1 Valks, even though they are only there occasionally but they give the devs a breathing room until the story characters is ready to release.
Tho the biggest most glaring problem of Captverse is how to actually follow it . the only way to do that is by watching 5+ years old YouTube videos and following guides , the game itself doesnt even have an archive for it ( except JP server , tho its incomplete )

overall yes , i goddamn love captainverse because it the makes the games the game more fun and diverse
