I think what makes a video game so good are the graphics and the story behind it. Also, how vivid everything is to make it seem like you're actually in the game. I think Grand Theft Auto fits in that category too, because it feels like you're really there when roaming the streets and going anywhere you want to. You can also go inside a car and drive it, with a radio that plays. The more realistic games are, the more I love playing them nonstop. If a game didn't have good graphics, I wouldn't enjoy it as much as I enjoy playing games that do. I play Call of Duty and the graphics on that game is really top-notch. The story mode is really crazy. A lot of people talk bad about Call of Duty: Ghosts (which I don't understand too much,) because it's the most amazing eye catching game I've ever played. But people do have they're opinions and I have mine, so I guess it's because people look at things differently. But yeah, these are the things a video game has to have to be great.
