Mmm AI, other than say TOAW and WitE, where the AI has a "fixed" map, AI's in random games usually have a hard time. Although I've read some players find it difficult to defeat the standard AI, let alone AI+. I find it sometimes challenging to beat AI+, I don't do AI++ anymore. I've had random games against AI++ where I had to battle each and every hex filled with dozens of armoured cars, hundreds of Inf, just too many troops for the AI and clearly not much fun.
I tend to play on large random maps, multiple AI's where some are AI+. Good fun to me. Ofcourse I'd pay double the price ATG costs if the AI was capable of doing a massive amphibious assault, or make a large carrierfleet *with* planes, and so on. The more complex a game becomes the harder it gets for the AI.
