Kabula

From BoardGameGeek:

In a fantasy Island, a magic tree, the Kabula, is held in a Sanctuary to ensure immortality to all inhabitants. The balance is broken when six deranged characters from Earth find themselves transported to this Island. Their surreal adventures include humorous encounters and heavy satire on several topics. Kabula is a competitive board game set in a uniquely twisted fantasy world. It blends a sandbox RPG experience with skirmish elements and a combat system comparable to that of a dungeon crawler. Heroes will develop to one of three possible personalities as they fight and tame monsters, explore dungeons and encounter peculiar quests. Eventually, they clash with each other in pursuit of the Kabula, the tree which holds the fate of the Universe. -description from the designer
