Half-Life 2 had too much outdoor action for my taste. In contrast to Half-Life's mostly indoor settings. As for scaring the player, I was disappointed HL2 went for the very tired pitch black, flashlight batteries only last a minute style cheap scares. It annoyed the hell out of me and when I replay I just skip that stupid part. Ravenholme was superb and I hope that's what they're aiming for, not Doom 3 monster closets and more annoying pitch black settings.
