SUMMARY
STAR TREK: NCC-1701 was a 3D exploration game of the starship Enterprise from the "Star Trek" franchise (the original series) with light gameplay mechanics built by a company called Gambit Realms, who used the experience to learn the Torque 3d engine for other purposes (although, based upon their website, that education hasn't yielded any significant results as of yet). However, the game has since been "Foxed" (or, in this case, Paramounted) and can no longer be offered on that website...
...Except for this curious link on their website, apparently forgotten by just about everyone (so far?) that features the game but with Occulus Rift support. I haven't downloaded the game from this link myself but the link looks legit. So, if you've always wanted to explore what a life-size Starship Enterprise from the original series might have been like, here's your chance and who knows when this version will be "Paramounted" as well.
