Simply put, this is the greatest PC game of all time.

User Rating: 9.8 | Half-Life PC
This game changed the way we thought about games and I am not surprised. The gameplay was very unique at the TIME and games had never seen the laws of physics and gravity before produced so beautifully. Everything in the game can be moved or toggled with (the best being the exploding microwave!) There are about 15 weapons in the game and they all have different properties and all can be used with a different tactic. The enemy AI was amazing at the time and they thought about the situation first before diving in and getting themselves killed. The sound is amazing and it is still probaly the ONLY game (bar Half-life 2) that the NPC's have conversations with other NPCs. It's funny to just watch them chat to each other. The story is immersive and addictive and you will be playing it for about 20 hours. Oh yeah, Counter-Strike is the best thing EVER!!!!!!!!!!!. Who cares if Half-Life 2 is out, YOU NEED THIS GAME
