1. The Walking Dead - took storytelling to a new level. Can't wait for season 2
2. Mass Effect 1 - the game that started it all (decision making that alter future entries in series) great story
3. Journey - No fancy voice acting/stories. But a great single player experience
4. Assassin's Creed 2 - great story, sucked me into the world
5. Uncharted 2 - great story, voice acting, fun gameplay
