If you've heard of the HD Collection, you've likely heard the waves of hatred many classic Silent Hill fans have given it for “ruining” their favourites with this “buggy mess”. I will say this now; it isn't as horrible as these fans would lead you to believe.
Perhaps I say this because I've never played the originals, so I had no lingering expectation. However, I can say that the Silent Hill HD Collection is the perfect option for those of you who, like me, missed their chance to play the originals and want to see what the fuss is all about.
I'll admit that there are more glitches than you would normally expect from a release of this time, but that does not mean that the game is unplayable. To the contrary, I hardly noticed them.
The plots of the two games, particularly Silent Hill 2, are moving and detailed, and are perhaps my favourite aspects. I would recommend it to people who are willing to give thought to a game's plot; I even used Silent Hill 2 for an essay, and it received the highest mark.
In summary, this might not be the game for you if you have strong and fond memories of the original SH2 and 3. However, if you haven't played either, then by all means, give it a spin.
