Let us get three more chapters, and we'll begin to see some decent effects of the choices we make.
I just read some new info on
Episode 3 at the Japanese wiki that deals with new events being added to previously released chapters after the fifth chapter is released. By the way things are looking, this seems to be kind of similar to the Sue and Bernie subplots of
PSO. (I mean in style, not story.) From what it says, by going back to play "Despair and Hope 1,"
if you S-rank the trial on any difficulty, a new scene is added where you come across a deactivated Lou unit. This opens up a new option in the fourth chapter where you can elect to have Lou accompany you during "Separation From Mother 2." Something was also added to "Prayer of the Holy Light 2" where if you S-rank the trial on any difficulty, a new scene will be added where Ethan and Lumia discuss something. This all leads into some big stuff in the fifth chapter, "The Results of Ambition," but I don't want to read too much into it, as I'd rather have a few surprises left for me when these chapters are released over here.
