Moral decisions in games?

[BlasterMaster]

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.

you're not supposed to pick in Shadow
you're supposed to get every ending
then you get the true ending

not that it clears much of anything up, but still

actually, i don't think they really had a coherent plot in mind
