Today we take you on a 20 minute adventure. Building, almost from scratch, a complete graphical adventure game with Drools. The code will be part of the up coming Drools 5.4 release. The game is based on Wumpus World, from the book Artificial Intelligence: a Modern Approach.
All Hail the Wumpus

For those wanting to try this now, you can use the latest snapshot build from hudson. It uses the new property specific extensions, so the examples cannot be run against older binaries.
