Well, indeed Spino, wise words. Let's not all forget that Rome: TW is a very complex game to program, let alone debug.

The graphics engine alone deserves a game in its own right, and the campaign map could be mistaken for Civilization, im sure.

The AI could not be added until the game world was finished, and seeing as how they put most of their time into making the game user-friendly & finishing the world, I can understand why the AI is sooooo crap.

Plus they also tried to implement a new AI system. Remember the multiple layer AI? Combine that with not enough time, pressure for user-friendly & accessible, the difficulty of AI in general, and you have all the answers you need to bugs, errors, rushed parts, etc.

Still...
