I got to the new Kaine stuff in Route E last night. Probably do it today and be completely done.
I gotta say the remake, while being great for many reasons and more accessible, also made the game more tedious than the original. The runs are longer because of the new seafront addition, and in the original there was only 1 filler run since Route B run has constant new stuff. Even the Route C/D run has a few new cutscenes (very, very few).
But replaying Route E from the start, at lvl.1 doing shit damage and not having your boar mount...ugh. Even speedrunning and skipping cutscenes was about an hour and 45 mins to get to the new content, and unlike Routes B/C/D which are still kinda fun to replay since it's NG+ and you have all your stats and weapons and magics, these almost 2 hours just felt like work.
Still, hey, actual new real content now. Will be interesting to see how this compares. Hopefully it's a lot better than the Seafront story they added.
