One of my all time favorites. It's generally linear, but entertainingly so. I've played through wizard and conjuror, never quite finished warrior. My fondness for this game is on par with "another earth" and Baulder's Gate. There's just something satisfying about it. I also find some of the details like little cheerful noise that bomb-critters make when they spot a target they can blow up and heccuba's candle going out in the middle of her big scary ritual very amusing. It's a pure game, just plain fun no real moralizing story or depth, just a fun world in which your character gets pulled through space/time can kill the bad guys, gain some equipment and powers and finally get back home to his wife who's hopefully stll making bacon. You won't learn a damn thing, it wont make you a better person and it won't strech hour moral fiber, but you'll enjoy every wasted minuite of it :)
