One of my suggestions for Ken should he have purchased the Sierra rights when they were up for sell has come to pass - I got an email this morning announcing that Gabriel Knight: SOTF is now available for download on GOG.com. Of course, the announcement was titled "Introducing Activision Catalog" and I nearly deleted it without reading. But it looks like Sierra games are on the way - they've also released the more recent Sierra RPG Arcanum.
I've really enjoyed GOG's releases so far - they package the games for download, and make them compatible with modern systems. It keeps the classics alive, which makes me happy. It also gives companies an easy way to make money off of these classics, which should inspire further delving into the vaults. Maybe it'll inspire someone with a little cash-on-hand to make an investment in the Sierra name... :)
