Actually, that would be an awesome idea… but for other reasons.
Just imagine: main character gets thrown into the video game world… but it is so utterly broken, that Main Character starts to abuse the system of the game to gain an OP advantage. Like finding that the effects of the potion stack or that he can become superman by reflecting the spell from the wall to himself and back.
Essentially he becomes an OP hero not because of his powers, but because he abuses bugs and glitches

Elder Scrolls isekai wouldn't be so bad. Especially Skyrim. Plenty of waifus and you already have superpowers unlike the previous main characters.

Until you inevitably glitch through the world I guess.
