What I meant was that no matter how you slice it, the characters that end up dead will end up dead, and the characters that will live, will live.
Do you save Duck or Shawn? Either way, Shawn dies immediately and Duck dies later.
Do you save Doug or Carley? Either way, one dies now, the other dies later.
Do you help kill or save Larry? He dies either way.
Do you abandon Lily or let her stay? Either way, she leaves the group within a few minutes.
Do you save Ben or let him fall? He dies soon either way.
The dialogue changes as the relationships change (which is very cool), but the plot pretty much remains the same.
Yeah, I understand where you are coming from but to be able to change the plot would be asking a bit much, I think.
You have games like Mass Effect series which is suppose to give you choices and affect the outcome but after 3 games and $180 later, you still don't affect the plot all that much. To ask that of a game that's $25 is a bit unrealistic.
It would be too much work to program for several different branches caused by choices you make.
