I see this is an older topic, but I found it interesting and timely (see Covid-19). Yes, I often play solo. Quick background, I have been playing A&A for over 30 years, so I am very experienced. As you get older it is often more difficult to get the band together for a game - and I am too old to get into online gaming.
After tiring of trying to get games together I started playing solo out of desparation I suppose. With that said, I quite enjoy it now - after getting over the initial weird feeling of playing an interactive board game by yourself. But as others have noted, from an analytical perspective it is not actually that difficult. Is it perfect no, but neither are your friends who come over and drink your beer, complain about bad rolls, and blame historical inacuracies for their loses…but I digress.
One must simply act in the best interest of the nation they are playing. For example, let’s say the Allies could threaten Germany’s capitol this turn, but you plan to attack on the next turn, Germany must protect the capitol as necessary to negate the threat - stay honest. I personally find the rolls, or more to the point the bizzare rolls, are the key to fun solo games. There always seems to be a handful of Yatzee rolls of ones that throw a huge monkey wrench into the best laid plans - just like real life.
It would be cool to have a specifically designed solo A&A game, but again as others have noted, building in the AI to handle all the variables associated with these games is extrememly difficult.
Anyway, hopefully there will be new games/puzzles to solve in the future: 1914 second edition, North Africa, Kursk…
