Through the goofy, into the serious+content
Erfworld has been one of my favorite webcomics for some years now. If you are a serious person, you might not give it a second thought. It is unrepentedly goofy, full of cute puns on pop and geek culture and set in a bizarre fantasy world that very explicitly follows wargaming physics. But if you are a serious person who enjoys that sort of thing, it also regularly rewards you with its characters' struggles with perennial dilemmas about love, identity, and war.
I'm glad that I am a goofy person who enjoys such things.
