At worst, it can be tricky at the beginning of a campaign, but as with any TW game, it gets easier the longer you get into the campaign.

ETW's campaigns are arguably more complex than any other TW game and there's a bit of a learning curve when you jump from the comparativley simple preocupation of producing an armoured meat grinding empire, as in RTW or MTW2, to building an economic empire that will can support it's own territorial growth.

The current problems (CTDs notwithstanding) are to do with the AI being, for whatever reason, unable to exploit the new features and mechanisms to the same extent as the player can. It can be a bit like playing Tennis against a child, or playing chess with someone who only know how to play draughts (checkers).

It's still fun though, especially when you are discoveringt he new aspects of the game. Any disapointment comes after, once you've absorbed them into your play-style.

That's my opinion anyway! :)
