I have been granted permission to release my Race for the Galaxy AI to the public by Rio Grande Games. It's now available at my website:
http://keldon.net/rftgBoth a source code distribution and Windows installer are available.
There's support for both current expansions, 2-6 player games (if expansions are used), and the 2 player advanced game. Note: goals are always on if using either expansion, and takeovers are always on if using Rebel vs Imperium.
I've spent most of my time lately on the new cards and rules from the second expansion, and not so much on the AI decision-making. Therefore, I don't think it's as strong as it could be. I can often win in most setups except the two-player advanced (a format either the AI is really good at, or I suck at). I hope to make some improvements in this area next.
Let me know if you run into any bugs. Takeovers, especially, are fairly new and complicated and I'm sure I don't handle everything exactly right yet.
Big thanks to Rio Grande and Tom for changing their mind about this, and also Wei-Hwa for sending me the great-looking card art.
