Don't go back. Never go back. Guess this is also true for video games. I remember loving these games, especially SH3, but this reboot is horrible. I expected updated controls, and at least partially updated graphics, but got the same Resident Evil era controls, horrible sound (try your best to avoid any metal flooring - trust me), and the graphics, while crisper, lose their edge.
I've read a lot of reviews over this game, and I've noticed one thing: Most of the people who give the game low ratings or harshly criticize it are people who have played the PS2 originals. This seems to be the case with A LOT of the reviews. Here's my two cents.
I played both Silent Hill games on this. Let it be noted, I never played the PS2 originals, so all of this was entirely new for me. Needless to say I enjoyed it extremely. I was happy to finally be able to play the two most critically acclaimed SH games, now in HD.
Like the title says, if you're a newcomer to Silent Hill in general, or if you haven't played SH 2 and 3 yet, this collection will be your cup of tea. If you played the originals on PS2, chances are you aren't going to have as much fun, because you'll constantly be comparing it to the PS2 version. That's just my opinion though.
I did enjoy both games a lot, the HD looks very nice, and even though there were a few glitches here and there, they weren't anything to ruin my experience playing these amazing games. The story to both was great, the gameplay was good, the music and sound were both amazing, and the graphics look wonderful and have a gloomy feel to them, as Silent Hill should.
Like I said, I played the HD collection without ever having played the original SH2 and 3, so that might be why I enjoyed it more than some people. Definitely satisfied me and gave me some good scares.
