Highly recommended. I played the demo (which is a level not in the full game) to death like a sex starved nympho in a cashmere lined room full of Christian Bale clones, and then I finally got the full game. One of the first things you notice is the obscenely vast sense of scale of this gameworld, interesting for its tension between the dizzyingly colossal architecture and the comparably tiny brilliant minds who built them and populate them. Acrophobes be warned. I cranked up all the graphics settings (except for volumetric shadows, which slowed down the framerates considerably but were atmospherically useless anyway), and Kyle's universe came into sharp focus with sheer sceen-lickable precision.
And all that before I finally got my lightsaber. Those of you who've played this otherwise underappreciated spectacle, you know what I mean. The lightsaber is as close as you'll get to a high tech sex toy surrogate. I mean, that mofo is up there with Alice's darkly twisted toy arsenal. And in combination with your increasing force powers, well....let's just say that it's practically sinful. Gameplaywise, there are near Half-Life moments where I would enter a room and all hell would break loose.
Another good recommendation: play it while your six-year-old nephew is watching. Many were the moments when mine laughed uncontrollably as I switched the lever that opened a hatch and caused a dozen storm troopers and imperial guards to get sucked out into outer space, screaming to their icy eternal stillness. Of course, I saved that part of the game just for him to watch whenever he wants. He asked me why the bad guys were after Kyle Katarn, so I made up a story about Kyle having a really hot ass and that all those imperial guards and storm troopers want to grab it, and Kyle hates that. Natch, right after that I entered a room with a bunch of them and one of them shouts, "Get behind him!" My nephew and I never laughed so hard together.
