No need to say that not having a lot of say in the story is necessarily a bad thing.
Being pulled along a certain path by "fate" or whatever

You can go with the flow to the end of the story, or you can seek out every bit of information, get closer to understanding what's going on and still going with the flow for lack of a realistic alternative.
Having "four different endings!" in every game can be a bit contrived at times, you know
