What's funny is it's not even a game!
It has a beginning, middle, end, gameplay, it's in an online store/database, and they've stated it is not representative of "Silent Hills." That sounds like something that qualifies as a game to me. The nature of the games landscape has changed with "alpha" and "pre-release" games becoming extremely common place in the past years. In the spectrum, PT is a polished work that was played by a large audience that responded positively to it.
It was a bad year for gamers if PT is considered the 8th best game of this year. I like the hype and all, but now people are going to expect this new SH game to be best thing ever. I'm worried about too much hype.
I don't think a subjective list's choice should ever be an indication of quality. After all, Nintendo was killing it with MK8, Smash, Toad Treasure Tracker, and helping Bayonetta 2 see the light of day. Now, if you want to point to the debacle of high profile games that are broken, that would be another thing!
At this point, I will take a positive hype around SH over what the general fanfare has been the past decade.
