I recently found out about this cool map generator that creates little minecraft worlds.
It's nice too play if you want a challenge and There still is a day and night cycle. monsters will spawn in shadows made by planets and all the different blocks are still there and the glowstone planets act as little suns at night.

WARNING: I would recommend using one of the pre-made worlds and you should make a back up of your saves.(you should already have made backups). instead of using the generator because it can Delete your save data!
