Silent Hill was rather scary when I was first introduced. Now though I'm more leaning towards Amnesia - The Dark Descent and Dead Space. I find some of the scares in Silent Hill more repetitive then in Amnesia or Dead Space. Although I'll give Silent Hill credit and say the story mechanics and puzzles really help to immerse you into the game.

My favorite video game series is Armored Core.... Well, Armored Core 4 (4 Universe.)

It's a mecha game, albeit with a renowned amount of customization and learning curves to suit everyones playing style. I still play For Answer, and I find the whole premise interesting. With three different routes and several companies to support you can really feel your an actual mercenary with an awesome mecha.

I'm also one of the most hardcore people you'll ever find about TYPE-LAHIREs. They are incredible lithe and beautiful machines, designed for close to mid-range combat. Their spontaneous quick boost and capacity for agile playstyle fits my needs perfectly.
