What's the story behind all crap?
 

I mean, serious.

Haunted House: Boom, a house, call it haunted although there's no freckin' Ghost or something. Kill all the monsters and get a key/prize. Wow, that's like, like, what the hell is it doing there?. I can get a player-house, and stuff it full with summoned monsters and call it Haunted House and it will only be a little bit difference.

Underground Dungeon: ... Okay, a tunnel, okay. But who build it? How did the monsters come there? Why did they link it to the islands? Was it a way for the kingdoms to interact with eachother during the war with the bomies?

Maps: Who in the name of hell would give maps to monsters, then put LOADS of items in them, and them coming back all the time?

Oh and these maps are way to strong. Level 1-3 is good enough, use the other monsters somewhere else, like the worms in a desert or stuff.
