Minecraft PC Maps: Any Suggestions?

As you all know, I have a new YouTube channel called "iAmNinjoe". In this channel, I do these videogame LP's (Let's Play), skits, and other stuff. I've been thinking and...well...I want your ideas about what Minecraft PC custom maps I should do. Mini-game maps count as custom maps (in my eyes). The only maps that are not acceptable are maps that have content that is inappropriate or content that has profanity. Sooo...please give me ideas.
