a crazy idea for a series

Hey guys so I had this idea that's been nagging the back of my mind for a good while.

So since I've yet to decide whether to drop this or rewrite this series, I thought I'd make a new series and do that for a while until either I bring the series back up or I just drop it.

The series is either going to be in either dc, solo leveling, or one punch man and the mc will be an avid rpg gamer(semi-retro) who opens his front door and enters that world without any powers…or so he thought.

He gains the ability to infinitely level up via the retro games like castlevania symphony of the night or castlevania aria of sorrow, maybe even final fantasy vii.

And he gets to keep and use the items he gains from the games and use them in real life.

So with that in mind, how do you guys feel about this?

And please! Comment here on which of the 3 worlds should the mc appear in?
