Well, I announced it already in other parts of the forums, but here again:
TripleA is up and running, and provides all kinds of A&A games including complete rulesets, enabling online live play, PBEM or local sessions (against the AI). Moreover, it provides some awesome maps for the advanced player (like New World Order - NWO). And all this within a normally pleasant and mature community.
Of course, the AI will be no real challenge, as can everybody having basic understanding of AI programming will easily understand. But it does a surprisingly decent job at the moment, thanks to many improvements.
