Just was irritated after paying for the game at releasedate and basically winning every single battle first try.
Then having the AI being unable to build armies that were challenging (even if you had no clue about the gamemechanics, which the manual did not explain.)
Basically I was able to knock out denmark in 1 year as Sweden by just marching the troops i had at start to christiania and kobenhavn.
It felt like "build something random, and move armies randomly at weak positions". The AI in eu1 was a bigger challenge and that one could not handle more than 2 targets per country.
We've been slaughtered for bad ai in games as well, but I'd expect that if you got a budget over 1M USD you'd be able to have at least 1 guy at AI for a year
