Is there a reason that the hardest difficulty is required? I'm unfamiliar with this game. Wondering if it was because you were the only runner. Maybe a category of either conquest on any difficulty?

Is there a different ending for doing both on the hardest difficulty? Thanks.

Hey lack! It was definitely because I was the only runner years ago and that's the category I played. The difficulty really doesn't make the game "harder" per se, it just makes the AI more annoying since it will attack you more often even with a troop deficit, which just wastes time. Since the two conquests are vastly different, they should be different categories (as well as doing them back to back in one playthrough as a third category). There should also be different categories for the World Conquest alone, since there are four different countries you can play as.

AFAIK, the ending is only visually different depending on which country you are when you beat the game. The difficulty does not impact the ending at all.

I see, thanks for your additions! I'll probably be hitting you up for tips one day. Cheers
