The AI is pretty good for learning the game. From personal experience having never played the boardgame, it takes quite a while just to learn the game mechanics and understand the basic strategies and strengths/weaknesses of each of the seven Major Powers. The AI has its weaknesses but it will provide sufficient challenge for a new player for a while. Even after several years I am still surprised by some AI moves, but moreso by mistakes that I continue to make and the AI takes advantage of. I still find it entertaining to a point, even playing Prussia or Austria and marching into Paris by 1809 if not sooner.
I'll go back to emphasizing the time needed to play and learn each Major Power. Every country is different and has unique capabilities. Austria has Insurrection corps. Turkey has Feudal corps. Spain has Guerrillas. Prussia can save manpower points for a rainy day. France and Russia have Artillery corps. Britain has its navy and naval options. So it takes time (months, years?) to understand how to use all these different features, and how they could be used against you in a game. I continue to find the learning journey to be enjoyable, despite some of the final results playing against the AI. I do get bored with the AI silliness now, but that comes from playing the game and getting past that learning curve.
I don't see any general discussion thread for this game
You must be really new! If you set the Display Topics filter to All Topics, not the default 365 days, you'll find plenty of discussion. This game isn't affectionately called "Empires in Arguments" for nothing.
