Well then I guess DMC4 and MGS5 chapter 2 were fine too then cause they did show new stuff and DMC4 had a character with different ability (which was great, but still the fact that I had to pretty much play in the same locations and fight the same bosses was kind of shit). Honestly I don't really care much about the side quests if they are going to be like what they were in route A, just fetch quests. I did like the little girl side quest though.... But it is a long action RPG with several quest. 40 hours in atm.
I only just now finished Route B, but the repeated content there isn't that bad. There's a lot of new sidequest, some which are pretty significant, and there's a lot of new story content as well. I imagine the future routes will be mainly new content.
The most important thing for me are newer locations....there are so few of them and yet the game reused the factory and the city ruins area far too much in route A itself and they'll obviously reuse them in route B now too. While interesting locations like the castle and especially the theme park were barely even used. The thing is you spend so much time in route A with 9S that I can only wonder how different it'll be in route B.
And you say future routes? How many of them are suppose to be in here?
