Well before this thing ends, I would just like to throw this last opinion here.
In a sense, games are absolutely art. Granted there are some that are simple,hardly any story at all, and have gameplay that an untrained monkey could learn. But aside from that, you have to remember that each game despite the simplicity, is made with just as much intricacy, meticulously, and precisely as any painting that you would see at the MoMA. It just has to be seen through the right eyes. If you're one of those people that looks at the game as a whole, and only sees it as a game to entertain the simple minded, then I would say that you live an empty life. But if you see that each detail of whatever game you're playing has been made with care, and by extremely skilled hands, then you can see the beauty of it. My boyfriend has a degree in animation, but all the time he works on his ability to animate characters. Granted I've only seen a couple of his animations, but once you see that when you get a person motivated enough, they can accomplish amazing things.
And so with all that said, Video games are absolutely considered art. By way of seeing that it takes talent to pull every single piece that makes a game, a game; story, animation, character design, etc, can make a masterpiece just as amazing as the Mona Lisa.
