Quest is a good Mahjong game. Not as good as Minassan, but easy to pick up and fun to play. The rules are a little strange, and you can use spells and etc to create an attack (some spells will give you a random tile, others will give you that one tile you need to win). There is no nudity, but you do have monsters that as they lose (2-3 rounds) strip down to reveal girls in their undies... funny if nothing else. The one nice feature of Quest of Jong Master is there is a learning mode, so newbies to Jong can have fun while learning the game (the computer suggests pieces to discard, etc).
