As you can probably tell from the title, this webcomic primarily focuses on MMORPGS, or massively multiplayer role-playing games. This comic satirizes, parodies, and generally pokes fun of almost all gaming tropes and conventions out there, but also plays some of them quite straight.
There are also a ton of delightful pup cultural references.

BTW, Richard, the warlock, is the greatest character ever. Of all time.
