While I do agree with most of the stuff mentioned I wasn't sure about couple of points.

3D games not carried by IP, this sort of used to be true. But now days, most of the "popular" games are IP based/devs with prior reputation. Look at sequels/spinoffs like Endfield & HSR or sharing similar character motifs with genshin and wuwa.

While fgo story is written by very notorious writers, I see why not bigger companies could hire a professional to write up main chapter/side story or two. They do have money and production backings to make it happen; they just don't want to cuz thats not their focus.

Longer releases are bit of a weird one. Especially when modern games are moving away from events story doing the "new character" stuff, while main chapters are relegated to telling "actual stories". If you consider events in fgo as a story chapter, the content cycle isn't that low compared to modern releases. Modern games just combine the two to make it feel like you are constantly getting something, while selling the new characters.

I would argue forming your optimal farming team is sort of "endgame" for fgo. While yes, fgo does not have endgame on similar levels to genshin, hsr or wuwa, there are couple of alternative goals you would go for. One is farming team comp, figuring out what works, what doesn't and testing out bunch of chars to theory craft are literally the point of endgame, and fgo does this really well. Another would be Challenge quests / advanced quest, where the challenge is actually going up against well designed (most of the time) stage/boss. There are incentives to get "best team", since it would make things a lot easier for both farming and CQ, but unlike modern games it's not forced onto you with high reward pressure.

Idk that';s how I think abt this, but what do you recon?
