Calling Dear Esther a game is a little misleading, but until 'interactive' (again, a word that must be used lightly. I kept wishing for the ability to touch or move -something-, just to provide some additional immersion, but alas.) stories become more commonplace, it will have to do.
Having said that, Dear Esther is undeniably visually stunning in some places. The story, though disjointed, is very athmospheric as well and compliments the piece.
Certainly not for everyone, but if you think this kind of thing might appeal to you I'd suggest you pick it up at the next steam sale.
