Take, for instance, the pun-based classes. It's trying to be funny, and it's been going strong for years.
It's a little ugly, but Kingdom of Loathing isn't trying to be pretty. Kingdom of Loathing is a sort of pseudo-mmo kind of thing, firmly embedded in the web interface, with drop down menus letting you select your attacks, and page refreshes for every new area. Play: Kingdom of Loathing | Developer: Asymmetric Publications
