This game is so sweet, i wouldnt rate it the best game of all time, but it is certainly in the top 10!

User Rating: 9.8 | Half-Life PC
This game revolutionized first person shooters. Its true, and if you dont believe me, ill prove it: This game managed to blend puzzle solving, platforming, and great first person shooting elements into one game. And it pulled it off perfectly. The AI is top-notch stuff, even today(dont listen to that r-tard mkattict1, hes an idiot) and they use cover and grenade you. Some games today cant even manage that! I got this game just before Half Life 2 and i have to say that it definatly set me up for a great story, with perfect atmosphere. The sound is also great, adding rock music at an intense fight really makes you pumped up! And also, that r-tard said that it had good graphics for its time, but i dont see how they even affect the game, so i think that they shouldnt hinder its score for coming out in 1999. It manages to make everything worth it, especially for $10.
