Although it appears to cover more than Christian game programming, the Christian Coders Network site contains information about writing Christian games.
The whole genre always puzzled me. How do you write entertaining games without pandering the same sex and violence that mainstream games offer? Where's the captivating concept, the heroic implementor, the effective distribution network, the proper motive, and the desired result? I hope that there is indeed room for relevant games with Christian themes in today's world. I hope that there are those out there with the talents that God can use on such works.
Even though older generations may not understand or appreciate the importance of video games to today's youth, there is still a need to explore this arena. I hope to make this a subject of some research in the future.
