Off the top of my head, Arthur C. Clarke's Rendezvous With Rama might make an interesting first-person game.
I don't say shooter, because it's not a shooty sort of story. And we have more than enough fucking shoot-em-up games, already—which i usually put in god-mode at some point, so i can just explore without being pestered by the token beasties.
I'd certainly enjoy exploring a virtual Rama. And the sequels offer yet more detail.
It could work as a text adventure, too. Planetfall on steroids. ;)
[Ooh! Someone should remake Adventure (aka Collossal Cave) as a first-person.]
