Shouta said:ACE2 didn't take that long as I recall, maybe ACE1? ACE3 definitely played the best of the original three to me.
Plus, shorter route times makes it easier to play on hard mode a second time.
IIRC ACE1 was about 40 hours, ACE2 around 30, ACE3 was 2 branching paths that were ~12 hours each.
ACE3 definitely played the best, but whereas ACE1/2 were one long complete storyline, ACE3 was like "play the greatest hits episodes from your favorite anime!" where each anime got like 2-3 missions and then the game was over. I did all the paths and got all 50 units and I felt unsatisfied by the amount of content.
Then again since ACE:R looks to be an original story and not just playing out eps from the shows (outside mission 1 of the game), maybe the story will be complete and satisfying even at 12 hour length. Probably about 25-30 missions per route.
