Moral decisions in games?

[Vipershark]

I only like this idea if it doesn't effect the story at all.
I really hate changing the story and not knowing which one is the real one.
But, if it was a side story like the Chaos Garden, then I really don't care what I do and its more entertaining.
But, if its like Shadow the Hedgehog or BioShock then its really hard for me to pick.

uh
what the hell do you mean "real" one, as if there is a "fake" story??

shadow the hedgehog has like 20 endings and only one is the "real" ending or something like that

I never got far enough to find out
