There's also a difference between "different" and "interesting".
Some games are different and boring. Some games are different and curious. I mean like, Dear Esther is different but it is terribly unexciting and none of its new ideas are any fresh or invigorating. Meanwhile, Mirror's Edge is different and while it doesn't quite execute its originality perfectly it's still a rather exciting mix of disparate elements that make it an experiment well worth playing. Taste permitting, of course.
