Fate Samurai Remnant found itself in a very compromising position where it isn't enough of a musou game to satiate musou fans and Fate fans might enjoy the story, the slog of having to play through the game three times (4 if you want to see everything) will make them hate every second of playthrough 2 and beyond.

I really enjoyed the story and absolutely loved the True Ending, but I don't think I could really recommend the game because of how much of a chore the game gets.

I'd say wait for an anime adaptation.
