Just to defend the advantage of not having much in the way of a story for a second. Ambiguity is a great thing in art. I've been ranting a raving about Quake 1 recently after rediscovering (Yet again) how awesome it is. To my mind it's single player has aged so so much better than, for example, quake 2 and half-life.
It's continued greatness could be attributed to its atmosphere, exploration based gameplay, the high speed, solid yet unrealistic, stylised gameplay mechanics, a great arsenal of weapons, well designed interesting monsters and the incredible level design. But it's worth noting that, unlike some retro games, cheesy acting and plot don't get in the way of the atmosphere one bit. But what if it had a good fleshed out plot and strong acting?
The plot in Quake 1 is about as minimal as it comes. There's no dialogue or cut-scenes. You can read the basics of what's going on if you want, but even then the exact events are largely left to your imagination. Not having a complete picture, you're thrown into an amazing, dark and hellish world and your imagination can try to fill the answers.
Could a great fleshed out plot have been added? Personally I think any more detailed explanation would have taken away from the atmosphere it has. If it was awesome the plot might have made something new and great in its own right, but it would have still lost what it has and what it has is ambiguous and beautiful.
