Boy this is a tough one to write about. How can I fairly review a game  that has resided on my hard drive since the very day it was released? For  the technical minded, Half-Life (H-L) is based on a modified Quake 2  engine, but the modifications simply blow Quake away in almost every  aspect. Valve made an excellent move with this choice. It is well known in  the gaming community that Quake's engine has some of the most stable  networking code in the business. Too bad the video compatibility is a  little odd. For the gamer at heart, this game may have a . . . half life  longer than Quake itself. Valve made a good move allowing the gaming  community to have the WorldCraft level editor and other SDK software. What  this means to the average player is that a simple jaunt to a good web page,  will yield every manner of new levels, characters, and baddies to download  and install to their hearts content. And with Valve's Op-for expansion  pack, this game will take up a large amount of space on a lot of hooked  players' computers.
