Just finished playing Journey a few hours ago. It was special.
It's definitely short but I thought it was well worth the price. It brought up emotions in me that I haven't felt from a game in a long, long time. It was delightfully whimsical, like watching a Miyazaki film or playing Shadow of the Colossus/Ico. They throw you into a world that's large with minimal narrative and let you explore a bit. You eventually meet up with a random person online and the only way you have to communicate is with a little button to chirp. However, if you manage to stick with the same person throughout the whole journey (and they haven't played it through a million times and try to rush), you'll grow attached to them and even start to worry when you lose where they went for a few seconds. The ending was pretty powerful stuff, I thought.
I'd recommend everyone check it out at some point. Your first playthrough will take around 2 to 3 hours and it has a few hidden things that give it a little replay value. I'm curious to go back to it again just so I can see how different it feels playing with another person, I became quite attached to my partner. I felt joy, wonder, sadness, and triumph. Any game that elicits an emotional response (other than rage) deserves a look.
