Going by Metacritic, Ken Levine is the most consistent 90+ Game Designer of all time.

I'm pretty sure Kojima has a higher average on his directed games compared to Levine, also Levine directed SWAT which is at 80.

No. I love Kojima but it has some low 80 games in his list

Nothing that he has directed . Kojima Productions releases a lot of games that he doesn't actually lead in development, usually with just a producer title with those 80 point games.
