We are very honoured you are interested in Freeciv.
One disadvantage of Freeciv is that there are many many rules,
and it's a steep learning curve for people. There are other
games which are simpler which may be better for student AIs.
If I haven't dissuaded you, then read on!! :-)

At the moment, there is only one AI engine per game instance.
It is not possible to have some races governed by one AI engine,
and the rest by another. One advantage of having client-based AI
is that different AIs become possible.

This code is already there, and could be easily stolen.

If you want different AI engines, then I think #3 is going to turn
out to be the easiest. (Oh, and it furthers Freeciv more, so we'd
like it better!! :-)

I would suggest basing it on 1.8. If you use CVS, and your
code doesn't change existing things too much, then you'll be able
to automatically get any updates made to the Freeciv codebase
(using the "cvs up" command).
Having said all this, I'm not Mr. Freeciv anymore, so others
will have other ideas. One advantage of Open Source software
like Freeciv is that you have an army of people who are willing
I wish you all the best.
