Half-Life 2 not only improves the formula of the first one but, it improves all FPS's in general
Gameplay 10/10 - The game runs very smoothly & maintains a flow that's very hard to describe. In certain areas of the game such as Ravenholm you really feel a sense of danger and fright especially when the super zombies are on hard. Also Half-Life contains some of the most intense fire fights without being impossible to survive in, and with intelligent allies on your side these can get very fun.
Graphics 10/10 - Though the Source engine is a bit dated it blew me away when I first saw the G-Man giving his speech. The addition of realistic lighting, face textures, and water can really set the mood of mystery as well as danger and horror.
Sound 10/10 - Like graphics, sound can really set the mood as well. The voice acting really lets you feel the gravity of the situation at hand as well as learn the complex story. Since Gordon doesn't have a voice of his own you feel like when other characters are talking it feels like you're Gordon at times.
Value 10/10 - The only problem is that the game is only 12 chapters while the first one was 19. While the chapters are less they make up for this by being extremly lengthy. In total I belive it has taken me about 50 hours to beat the game on hard. While the Deathmatch version wasn't originally shipped with Half-Life, Counter Strike: Source is a worthy addition that gave me many insomniatic nights fueled by Mountian Dew finding new ways to survive. Tilt 11/10 - From the above you can see I really like this game. I believe that this game deserves the 30 something awards it has recived and should be counted in the list of best shooters of all time.
