I'm on a DnD-isekai-lit-rpg kick right now, I just find the genre hilarious. I know, nerd.
The Noobtown series has some hilarious characters, especially Badgelor, the homicidal, sociopathic badger, and Shart, the needy, sarcastic demon.
Drew Hayes' NPC's series has some really good plotting, really any of his stuff.
The Critical Failures series, funny, not as funny as Noobtown, but more plot centric, worth a read.
Anyone got some other fun genres to check out? Before this I did 'pathetic/inept villain protagonist' and 'boring monster', might go for something meatier next time. For a lark did 'bad Jane Austen homage's', that was hilarious, when viewed as comedies.
