As far as I know this was one of the pioneers of the "immersive" sim genre. A weird (but really functional) mixture of FPS, puzzle game, point'n click, stealth, etc... 3 years before Deus Ex.
With an interesting plot and very solid aesthetics. I'd say that this - like Ultima Underworld and other games in the history of videogaming - tried to go where no-one had yet tried to go.
The only cons (at least at the time of the release) was that the 3D graphics were very demanding in tech terms. Which was circumvented by the small game screen (which also doesn't help a lot, making the game a bit clunky).
Personally I think the game's a bit an "UFO". Weird and experimental, but very playable. If anyone really likes things which try to escape the "norm", then try this. Just don't forget that it's a 1996 game, working on 1996 tech.
EDIT: the game features combat (although not really that much, if memory serves me well). So people who are more into a relaxing experience and hate action in their adventure games should be careful.
