it's great to be able to fight in the different locations. i know there's some landscape variability, but it doesn't really compare to the different castles. they're each unique. (well, kinda). some castles you can take the initial wall very easily, others the outer wall is a total *****. there's different styles of construction. sometimes the ranged defenders have a huge advantage and sometimes not.
it'd be cool if someone wrote a guide the castles of calradia. under the pen name artinemeer. with picture tours of the castles and strategies for besieging each one.
yeah,the details can be obnoxious sometimes. but i think the game would really be lacking without sieges.
