Despite what all the critics have to say, I really like Quake 2. There's just something about it that keeps me playing it over and over.  The graphics are a noticeable step above the original Quake's, and the gameplay is nice and sturdy.  The missions in Quake 2 have a flowing feel to them that makes you believe you are working towards something.  The sound is superb with all the explosion sound effects one would expect for this type of game, and the opening music in the first level is a great mood setter for the game.  The ending is a little brief, but ID has never been known for producing storylines of epic proportions anyway. Online death match play, while not up to par with some other games of the same genre, is still quite fun and adds lots of replay value. If you're a fan of first person shooters, get Quake 2 now and pick up the mission packs while they are still available.
