All of the games I have beaten that I regard as a 10 / 10 ranked. To me, a 10 / 10 isn't a perfect game. That's not really possible and imperfections can sometimes make a game better than if they weren't present. Striving for some idealised "perfect" game is just going to limit what games we can respect. A 10 / 10 to me is something that truly moved me whilst not having any flaw big enough to damper my experience. A lot of these games literally changed my life.
