His walkthroughs are some of the funniest things I've ever read in my life.
They are slightly longwinded (it's an entire walkthrough of a game told through screenshots and text), but the way the author writes is just hilarious, and he even interjects sometimes by writing his own conversations between the characters, often to Lampshade how ridiculous certain plot elements are, as well as how stupid the characters themselves are.

My favourites, all incredibly hilarious are these:
Final Fantasy 7: Dirge of Cerberus
Drakengard
Clock Tower 3 (the most recent I read)
Nier
Resident Evil: Dead Aim (the first one I read)

If you have time, I would highly suggest reading one.

Do note that there is lots of swearing though, and probably some references to sex-related stuff (though it's still SFW)
