"Genuinely great stories..."
Yeesh. Genuinely great video game stories. That's a tough one.
Bioshock - Philosophical underpinnings. Deconstruction of typical video game structure that adds to the overarching plot. A handful of interesting characters. A twist deserving of the term. All set in an undersea objectivist utopia, built on the incredible ambitions of a would-be industrialist philosopher-king. Said utopia now fallen into ruin, its halls stalked by gibbering madmen and lumbering guardian golems. Yeah... Bioshock is the good stuff.
Shadow of the Colossus - Minimal but perfectly sufficient, doesn't feel the need to explain any more than necessary. Thought-provoking (literally). Actually manages to achieve a sense of pathos. Also, best horse ever.
And... that's it.
Sadly, those are the only two game stories that I can call "genuinely great" with a straight face. The only two that I could hold up to the works of other mediums without being ashamed of my favourite pastime. The only two that I could present to non-gamers as a demonstration of what games are capable of. It's a bit disappointing actually.
Don't get me wrong, there are other game stories that I like, love and adore. I love the story, setting, characters and storytelling methods of Half Life 2 and its offspring. I love the characters, dialogue and setting of Mass Effect 1+2. I love the Portal games to bits. And there's plenty more... Beyond Good & Evil, The Longest Journey, Metro 2033, Amnesia: The Dark Descent, Mirror's Edge, Sands of Time, Fallout 3, Ico... yeah, it's a long list. But I'd just be kidding myself if I tried to call them "genuinely great".
Then of course there are the games I haven't played. Silent Hill 2 may deserve the praise it gets. Chrono Trigger sounds interesting. Planescape Torment might meet my requirements... if I could just bring myself to keep wading through the damn gameplay. So hopefully there's still some awesome stuff out there.
Oh, I don't bloody know.
