I have played the old ACW and BOA and now AJE and the ROP Gold. In my opinion, the AJE AI is very good. It is vastly improved over the old ACW, BOA and, in my limited experience so far, with ROP Gold. With the old ACW, BOA, I felt you could only get a really quality game playing PBEM. I am not sure yet about ROP Gold but I suspect PBEM is going to be necessary for a really good game. AJE has shown me that I can have a very enjoyeable game against the AI. I am assuming the AJE AI is so superior because AJE is a newer game with the latest version of the AI.
So I am wondering what other AGEOD games have an AI perfomrance at a similiar level of AJE? Perhaps, RUS, others?
