I've noticed that my opinion of a video game is sometimes largely dependent on the main character.  One of my favorite games of all time, Red Dead Redemption, is a third-person shooter which takes place in a wild west frontier town, so a lot of the action is on horseback.  That type of game seems unappealing to me on paper, but I gave it a shot and totally loved it.  The way the story was gradually told through interactions with different characters made it surprisingly thoughtful and immersive.  But I also had a strong attraction to the main character, a law-abiding, even-keeled cowboy with a strong sense of justice and a gritty voice.  The voice actor chosen for the part was spot on.  I think any story where you think, "I want to be that guy" means it's a good story and a good character. 

Contrast that with the video game Watch Dogs, where the main character is a cyber criminal who steals money from people on the streets and who's voiced by a man with the weakest, most unbelievable, unemotive voice I've ever heard in my entire life.  The game itself isn't terrible, but the main character completely kills it for me. #entertainment
