It's not really that different. You don't need fancy code, you just need something more readable than huge blocks of unformatted text. Dreamwidth's default layouts are fine for most games, especially if you turn off some of the useless sidebar modules.

Profile coding is something people do for their own personal lists of characters they play, as a way to show off their design skills. It's not necessary at all. Believe me, a game with a solid premise and organization and clear writing will stand out even if the layout is ugly. You can usually find someone willing to code it up nicely for you, too.
