Just played Journey for the first time. I was fortunate enough to have played the entire game in one sitting, with one person, who hadn't played it before either.
I loved it.
I found the minimalistic visuals and music absolutely perfect, and the way the world communicates its rules I found to be really well implemented and natural. The joy I got from the slalom-style sequences and the tension I felt when you first encounter the "baddies" was incredible; easily one of my favourite games in many years.
And, I'm not ashamed to say, I was moved to tears at the end :)
