Gamespot - House of Horrors
Jess McDonell (http://uk.gamespot.com/users/tempertress/) and Zorine Te (http://uk.gamespot.com/users/Zorine/) of Gamespot Australia play scary games each week in a live stream. Go to my blog version of this list for clickable links.
All Twitch.tv links contain archives of all the episodes in full. Here is the Gamespot page that goes into more detail about the show and provides links to highlight reels for earlier episodes. From the Lumber Island episode onwards, the episodes are archived in full at Gamespot as well as Twitch.tv, but they are generally shorter, lasting about an hour. Episodes can also be accessed via this show page. Bear in mind that the earlier episodes contained there are in highlight form only. The Gamespot archives are usually available in 720p, unlike the Twitch archives.
