Naturally every game has a beginning and an end, and getting to the end can often be considered 'winning' the game. But if you break down a game to its core elements, that which it distinguishes it from other forms of entertainment, you are left with two things: Content and action. Content is everything there is in a game, and action is everything you do in a game. Both of these are limited: The only actions you can do in the game are the ones it allows you to, and there is not more content in the game than the developers put in it. When you compare this to movies, for example, the only way in which they differ is that they lack influence. 'Movies' being used in the broadest sense of the word, because you can compare Star Wars to Mass Effect in that they are rich in content, but you can also compare Tetris to a stop-motion video made with post-it notes on youtube, which are low in content. Both are entertainment. Then if you take another dimension out of the movie, namely, time, you are left with a picture. And you can only fit a finite amount of content in a picture. Then you can create a game with the picture by adding an action, which gives you, say, a game of spot the differences!
So there you have the main genres in which art is made, deconstructed. What I'm trying to say is that adding a dimension to a form of entertainment has nothing to do with whether or not it gets to be art. A game like Zeno Clash - my all-time favorite, obviously - is brimming with imagination and wonder, so this game qualifies as art in my book. It's not about being able to win or finish something, it's about getting engaged with it. The longer, the more, the better.
