Oh there is SOOOOO much to love about this game. In fact I found a song that matches my feelings of this wonderful masterpiece.

Chainsaws to witches and rainstorm-filled ditches
Baseball bat bonking clown noses for honking
Ninja swords, crowbars, and axes swing true
These are all why I love Left 4 Dead 2

Jockeys go jumping as chargers come thumping
Putrid and vile girl boomers hurl bile
Spitters spray traps of acidic green goo
This is why we all play Left 4 Dead 2

Twisted dark theme parks and funny new remarks
Murkey muck mires and buildings on fire
Thunderstorms, daylight, and so much else new
These are why you should play Left 4 Dead 2

While you boycott
While you nerdrage
While you cry boo hoo
I'm killin' zombies with all of my friends
In left for dead, part two

This is why I want a gaming laptop known as the Toshiba Qosmio for my sweet 16 in June. Along with Left 4 Dead 2, and a surround sound headset for online speak. =3
