Incursion: Halls of the Goblin King is a freeware roguelike game based on (but not strictly adherent to) the mechanics of the d20 system made available under the Open Game License by Wizards of the Coast. The game boasts 9 races, 10 classes, 45 skills, and 17 gods all of them very well described and implemented. They require totally different strategies to be played effectively, though one can also decide to play as an atheist or a polytheist.
The game is unfinished, but complete enough that there are many people who enjoy playing it. It is currently maintained by someone other than it's creator, as it's creator has moved on to other interests.
According to the it's creator, Incursion: Halls of the Goblin King is "a promo game for the upcoming roguelike epic Incursion: Return of the Forsaken", which will feature overland map, multiple dungeons, towns, more prestige classes and other features. Return of the Forsaken was slated in the best case scenario for a release in the last quarter of 2011.
A detailed tech doc about the game is provided here. It could prove useful in roguelike development.
On 2013-04-14, it's creator posted noting that people might as well consider Incursion dead. Having moved on to other interests, he no longer had time or interest in maintaining it. On 2014-03-16, after inquiries offering to maintain the codebase and fix the bugs by various parties, he posted to the Incursion google group announcing the release of the source code for the last couple of released versions.
The Source Code
The official released source code can easily be made to build, following instructions given in the release post. However, it is based on an old unsupported version of Allegro, which is the cause of many of the bugs that have troubled users. From the display not updating, to the keyboard not responding.
