we think that the AI is quite competitive with other game AI's, and that if you use the play levels, you can make the game very competitive for yourself
Joel, thanks for your comments. All AIs are limited to some degree. I've actually been impressed by some of the things GGWAW does, like kicking me out of Italy a couple of times, so I agree that AI is competitive. My remarks were focused more on what can be done with mods to enhance solo games, given the current AI, rather than criticize it.
Reading through harrybanana's Allied Strategy Guide, there are a lot of good ideas that could be implemented in the ai.txt file regarding build and research priorities. Something similar for the Axis would be good. Maybe the AI won't care worth a hoot, but so what? If it doesn't matter, as Lebatron asserts, then it doesn't matter. At least we could get something perhaps a little more challenging, or more historically correct (like building airborne, etc.), particularly if we play solo and use the AI to handle research and production. I'm surprised there aren't some mods that already try to do this.
Another option for more challenging solo play is to create different mods for Axis and Allies. Beyond the difficulty levels which only adjust supply, transports and attack help, different mods could provide additional handicaps in the form of more units, research advances or adjustments to various regions. I wonder if placing a resource in Libya would help the Axis AI defend it longer rather than abandon it at the first sign of stalemate in Egypt. There are things that could be done. I did this with Strategic Command, with limited success. Others could try with WAW.
I do play WAW occassionally, but I do not have the time to add this to my list of projects. Strategic Command 2 and Anglo-German War are keeping me busy these days.
