This is by far my favorite game of all time... I have to admit, this was the first game I actually might of shed a few tears.
The journey you take with the protagonist (Lee Everett) in keeping a little girl (Clementine) safe makes you feel very determined to teach her how to survive during the zombie apocalypse. I loved the fact that you are faced with many difficult decisions that can slightly alter the story, there will be many times you may question the decisions you make throughout the story.

Pros:
-Amzing story line
-Feel emotionally attached to characters
-Makes you emotional
-Awesome comic style graphics
-The descision you make changes the story
-The music is perfect
-Great voice actors
-zombies

Cons:
-A few glitches here and there

Overall: 10/10

So if you had not played this game yet, you should 100% buy it and let the rollor coaster of emotions take over.
