an idea for this game from pso

I'd like music for your room since some PS games had that for housing.

I dont think this is specifically from PSO, I know WoW has rare bosses too, but it would be neat, particularly if they were hiding in some room most people would skip. Might encourage more people to go through every part of the dungeon

PSO actually came out in 2000! but I'm sure other games have had rare enemies before that, however I don't know.
