FINE! I'LL ADD TO THE DISCUSSION JEEZ!
Here's the thing about defining art, it's a really hard thing to do. The more criteria you add to what is and isn't, the more wrong you usually wind up being. People have been debating the "what is art" question for thousands of years, and the closest thing to an agreed-upon definition is it must A: be a piece of creative expression and B: have no purpose other than itself. The problem you run into when asking "is a game art" is a game isn't just one thing, it's two. There's the game part, the rules, the objectives, how you win, how you lose, the actions you perform, the physics, all of that, and there's the creative part, what you see and hear and the narrative. The point where things get tricky is, each part relies on each other equally, the game facilitates the art and the art facilitates the game, which makes things more akin to a piece of industrial design or architecture. The question you're asking when looking at games isn't "are games art?", it's a much, much bigger question than that. You're asking "is design art?", which is a really difficult question to answer.
