Take a look at wildfiregames 0ad, if you like RTS. 0ad is an open source RTS, where its easy to write your own AI in JavaScript.
A much bigger challenge would be an AI that is able to walk an avatar in Secondlife. First perhaps easy walk on the roads in mainland, later walk on arbitrary land, and the real challenge is walk inside buildings. A cat bot that does not fall into the lake, might even be a good seller.
