Snippet about the jRPG called "Dubloon", Source :
http://www.rpgwatch.com/show/newsbit?newsbit=15318One thing I really like about Dubloon is the magic system. It’s actually a pretty standard RPG magic system, except that you don’t cast spells with magic points. Instead, your characters have alcohol levels. The alcohol levels go down when your characters use spells, and can be replenished by drinking hard liquor. As your characters level up, their alcohol levels increase. It’s never stated explicitly, but I like to think that your characters just keep getting more and more drunk as the story goes on. It would certainly explain some of their erratic behavior.
