A 10/10 game does not equal a perfect game. It's simply one that has gone above and beyond in most of its aspects and deserves the score. There's still going to be bugs, there's still going to be some issues with the gameplay. A ten is when those aspects are so minor that they don't affect the score. When the gameplay, control, sound design, music, graphics, every fucking thing comes together. And even better, it's arguably something you can come back to multiple times, and you still consider it a ten. Not a speed runner amount of times, but something you can still come back to a decade later and still love all over again.
