The first Half-Life youre just a scientist on a routine day at work. An experiment goes horrendously wrong and youre forced to defend yourself against the horde of creatures that youre trying to explain to yourself why the hell everythings going apeshit.

I like the fact that your just a joe blow suddenly kicking ass versus a Duke Nukem type. Luke Skywalker started off as a geeky farmer boy. He ended up pretty hardcore. That whole warriors journey thing.
