As one of the 3 people in the universe who didn't much care for the original Half-Life, I was hardly awaiting with baited breath the release of this sequel. The things I didn't like about the original, namely the clunky and flawed controls, dated graphics even for 1998, outweighed the undeniable genius of the game as a story. I wasn't ruling out Half Life 2, but I was much more interested and looking forward to Doom 3.
Fast forward to the present. Having just built myself a top-notch gaming PC capable of running both games with ease, I took the plunge, but decided to install and play Doom 3 first. My initial reaction to that game --awe at the graphics and production value, creepy atmosphere-- was quickly replaced with tedium and boredom as the game played out like a 21st century scavenger hunt (find the key card! Get lost in the dark!). When I played Half-Life 2, however, I was BLOWN AWAY. The graphics are as good as Doom 3, but the big difference is that you can actually see them, because the entire game is not in dark tunnels, but rather takes place over a variety of terrains, ranging from beautiful coastline to wonderfully post-apocalyptic cityscapes. This game is truly deserving of all of the "Game of the Year" awards, and here is why:
GRAPHICS: Simply stellar. The textures are terrific, and the water effects are super, second only to Far Cry. The character models are very nicely done, and the way their eyes follow you around the room is both creepy and amazing.
SOUND: Very, very good. The sounds and music are very well done, and complement the game's moods quite ably.
GAMEPLAY: A gift from heaven. The game engine is ruled by physics so real, you're going to try picking up every object just to see what happens. A brick feels and reacts different that a doll, a tire swing responds realistically to a push, and bodies fall convincingly when shot or falling. The control is simple, smooth and effective, and the weapons are generally balanced. I wish there had been a better sniping weapon than the crossbow, but hey, that's what mods are for!
STORY: Again, stellar. It's so noticeable when a story grabs you, and when a story is just filler, a pretext for the setting of the game. In Doom 3, I couldn't care less why I was there. I certainly wasn't about to read the myriad boring PDA's you find on corpses, and the story is really trite. Half-Life 2, much like Knights of the Old Republic, makes YOU the star of the game, and gives you little chunks of info, but never overwhelms you with random names that mean nothing to you. As a result, you internalize the info, and actually come to care about the other characters. The scripted scenes are always logical and never forced, and they are just plain funny at times. I can't say enough about the great immersive world of this game.
NEGATIVES: Much like everyone, I dislike the "Steam" program which basically means that each time you play half life, you need an active internet connection. It's the company's way of authenticating your software, and while it's logical to be paranoid, (after all, this game's code was famously stolen by a hacker last year) it's a bit much. That said, most people have internet, so this is somewhat moot.
OVERALL: I personally don't care for online games; I find that people often act like children or jerks, and that the few games that are fun to play in multiplayer are shooters like Unreal Tournament of the Battlefield series. I can't express enthusiastically enough how happy I am to see that a game developer still cares about putting out a polished and amazing single player game.
