Edit: still a good game, but in a 5 or even 4 man game going last is too big a disadvantage in my view.
agree with most of the below - this is a great game where the tactics change a lot depending on number of players. Alliances are also less influential than some other boards like CC / Ants. The only thing I'd change is the final stage, going for the crown - perhaps there should be the facility to be able to defend against an attack from the crown, rather than it being a fait accompli once the crown is captured?
