Have you ever replayed a game so much that you became a master at it?

[4k1x3r]

Mass Effect 2, I played the first 4/5 times but the second over 10 (and the third 2 times) because I don't know, I wanted to test things and because I liked it so much.

God Of War 3 too, because I wanted to platinum it ô/ Must have finished the game close to 10 times too (before I moved out I also finished TLOU 3 times but had to stop, was on my way to fourth and more).

And as someone said above Prince Of Persia WW, because it had the Sandwraith and some cool story, but most of all badass motherfucking Dahaka with metal/rock music, what else!
