The petition gives some great pointers to making a great Silent Hill title, such as letting veteran developers take another whack at it, along with taking the time to make the game play mechanics easier, but giving you that feel of being trapped and scared to death. The art, the style of characters, voice acting, and of course the music composition are all elements that need both time and the right people at the helm to deliver a great release. SH 2 was a great example of that, and perhaps could serve as at least part of a catalyst for future releases.
On another note, time pays, if you use it to also make sure the bugs are ironed out. Downpour suffered a bit from graphical glitches, and it is kind of hard to be afraid when you walk down a hall and part of the ceiling is missing. So if you agree that the series needs a complete return to what made it so great, I invite you to sign the petition and add your voice to an already growing list of others.
Because there was a hole here. It's gone now.
