I agree. Oftentimes, branching storyline games tend to be weak in execution.

It ends up being either (1) the same story with 3 slightly different endings or (2) three completely different stories, supposedly linked together.

I think the best executions of this genre try to do something creative with the storylines and tie them together. If Alice does something in storyline A, perhaps when we go down storyline B in the future we’ll realize why Alice did what she did, etc.
