Another idea is an OC gamer who creates a virtual reality game based on Fate Stay Night. But then something goes wrong, and the game world and the real Fate Stay Night world start to merge. This could lead to all sorts of interesting scenarios, like the OC having to team up with in - game characters to fix the mess while also dealing with the power struggles in the Fate universe.
An OC could be a gamer who is a huge Fate Stay Night fan and somehow gets the ability to enter the game world during their playthroughs. They could then try to change the storylines they didn't like in the original game. Maybe they befriend a Servant that was originally an enemy and together they rewrite the fate of the Holy Grail War.
One idea could be an OC who is a gamer in the modern world suddenly gets transported into the Fate Stay Night universe during the events of the opening sequence. They could use their gaming knowledge, like strategic thinking and quick reflexes, to survive and make an impact on the Holy Grail War.
One interesting concept could be how the original Fate Stay Night mechanics interact with the gamer OC. For example, the OC might have unique abilities that change the way the Holy Grail War is fought.

One interesting concept could be the unique abilities of the Godlike Gamer OC. Maybe they have skills that are different from the regular Fate Stay Night characters, like being able to manipulate game - like elements in the Fate universe.
Another idea is the ability to hack the Grail system. In a fanfiction, the character could have hacker - like skills in the magical world. They might be able to change the rules of the Grail War, such as altering the summoning conditions for Servants or even adding new rewards.

In this fanfiction, an interesting aspect could be the new ways of summoning Servants.

This could bring in Servants that are not typically seen in the original story, creating fresh and unexpected interactions.
One interesting idea could be exploring different routes for the characters. For example, what if Shirou had chosen a different Servant at the start? Another could be delving deeper into the backstories of the Servants, like revealing more about their lives before they became heroic spirits. Some fanfictions also play with the concept of alternate universes, where the rules of the Holy Grail War are changed completely.
One interesting concept could be the unique gaming mechanics that are incorporated. For example, how the characters' abilities are translated into gaming skills. It might also include new types of magic or powers that are designed with a gamer's perspective in mind.
One interesting concept could be how the gamer elements interact with the existing Fate Stay Night universe. For example, the protagonist might have a gamer interface that shows stats for the Servants, which could add a new layer of strategy to battles.
A common theme is the struggle for power. The OP gamer OC often has to navigate the complex power dynamics in the Fate Stay Night world. Another theme is friendship or camaraderie, as the OC forms bonds with the other characters.
