The story itself will probably be fairly linear, honestly. The branching chapter 4 is the only time branching of this caliber will happen, and it’s very likely that which missions you do will only change a few small things.
This is likely going to be one of those “mostly-linear-with-a-couple-branches-here-and-there-where-the-only-choice-that-really-matters-is-the-last-one” kind of deals, as ashamed as I am to admit it.
Edit: This is only partially true, come to think of it. The choices you make will have an effect on which ending you get, but the “core” ending is based off of what you do in the final choice.
That’s one of the things I’m hoping to fix with the side missions, to a small degree. Each one will have a small sub-story planted in revolving around one of the characters. Except one of course, since there’s only 3 missions, but he gets his little story later.
I didn’t think of that last part. That’s a pretty good point. I’ll mull it over and see if there’s any way I could make it a little more obvious.
Thanks for your comments. I wanted to ask these questions to see if A: there’s anything I need to change in the currently-released content, and B: to see if I need to tweak my plans for future content.
