The problem with decisions in games mattering is that no they fuckin' don't. They don't. At all. Nothing you do actually matters. It seems like it does, but it doesn't.
And the killer is, nobody seems to consider messing around in a sandbox to be part of a story, which is just ridiculous. I mean, do biographies only include important life choices? No.
Yeah, games can be more than fun, but the big problem with story in games is that you can just hit "New game" and nothing you do will be permanent. Sure, you might still get emotions, but it still does not matter except at that particular moment when you're getting that particular emotion.
What the fuck is a "Meaningful choice" anyways? I see it brought up in story threads a lot (Maybe not here yet, but a lot), but I don't know what that phrase actually means. How does a meaningful choice differ from one that's not meaningful? What makes a meaningful choice meaningful? What makes it more special than deciding to spare one pedestrian in GTA or not going on a rampage in saints row?
