I very recently bought a PS3 for the sole purpose of playing Journey. And holy mackerel, was it ever worth it. Journey *is* an adventure, if you accept the idea that your character can fly and leap, with an element of platforming, and you are joined at random by a companion (an anonymous gamer playing at the same time as you), and you travel and collaborate together. I can't find enough good things to say about Journey. It's art, it's inspirational, it's majestic and above all, it has an emotional impact like no other game I've ever played.
So yes. Journey.
