Might of missed a side quest. I'm on the hard difficulty, just reached Pelennor, Fields(haven't played it in weeks)
I've beaten the game once on Easy but didn't complete it at 100%.
To really beat the game you've got to defeat Sauron with all Attacks of Speical/Light/Shadow,Craft items done, all attacks learned, on every player. and have 100% completed when you beat The Eye.
Which I'm almost done with! Only problem sports are learning Craft Items for Benethor, and then Hadhod's last set of attacks for SP and AC.
So far, I've only got two Characters who have completely learned everything, Idral and Elegost.
