Okami looks, sounds and innovates the part to fit as an artsy game, but the controls are quite hard to master for someone not used to modern-day-gazillion-button-controllers.
I'd probably sucker someone in with Prince of Persia. While its stages are a lot alike qua visuals, it's actually very nice on the eye. Level design and camera angles combined show you all the possibilities and where to go upon entering a new area.
Enemies and areas they control are visually dark and smudged, giving one the natural feeling that there's a stain that needs to be wiped off the land. After cleansing, everything turns pretty, green and colorful. Inviting you to go discover the secrets of the world.
While playing the game, it feels very natural, sliding, climbing, jumping, falling. It's directed enough to keep you going, but free enough to make you feel like you're in complete control of all that happens.
And of course, the game is extremely forgiving, fall down and you'll be pulled back up ad infinitum, trial and error gameplay with no form of punishment, just encouragement to try again.
Personally, I think PoP was an enjoyable timekiller, but I don't care much for it. Nor do I believe games can be considered 'art' just by themselves.
Games are interactive; decisions made by the player, and whatever input is received affects the way a game plays and is displayed.
The God of War example in the article can be applied here. Where one player can make GoW feel like a game of running around smashing things and buttonmashing through fights, another can turn it into a perfectly orchestrated masterpiece of massacre.
You can beat the game by spamming one attack over and over again, but you could also chain together endless combos, combining the flashiest moves in perfect harmony and feel like you're actually playing the game rather than exploiting it.
That may be a vague example to some, but I'll believe that my point is pretty clear. Games aren't art, and no matter how hard anyone tries, they'll never be.
Canvas and paint aren't art, it's what the painter does with them that makes it art.
