Finished the route. Very sweet. I think I liked Ran's route better (Ran's just more fun of a character, IMO), though I found Isoroku's route significantly more difficult, mainly thanks to getting dogpiled right after entering it (with Monster Army joining in shortly after, no less). Fighting a 3-front war in Sengoku is no joke, the only way to survive is to make full use of permits.
Did you guys finish all the routes? I always finish one and then take a long break from the game, so I've still got Kenshin's to look forward to. Also what's the actual "canon" timeline of Sengoku? I know it's supposed to be the True route, but since Rance made references to Isoroku's kid in Magnum, it's obviously not that simple.
