For those interested in indulging in some Sierra nostalgia:<p>SierraGamers (<a href="http://www.sierragamers.com" rel="nofollow">http://www.sierragamers.com</a>) is a lively forum maintained by Ken Williams, original founder of Sierra.<p>Quest Studios (<a href="http://www.queststudios.com" rel="nofollow">http://www.queststudios.com</a>) is a great site dedicated to the music of classic Sierra games, and also has a pretty good forum.<p>ImagiNation Revival (<a href="http://innrevival.googlepages.com" rel="nofollow">http://innrevival.googlepages.com</a>) is a reimplementation of the ImagiNation service, which can be used with the original INN client (under DosBox with the serial port mapped to telnet).<p>And since this is Hacker News, The Ultimate AGI & SCI Web Site (<a href="http://agisci.classicgaming.gamespy.com" rel="nofollow">http://agisci.classicgaming.gamespy.com</a>) is a site dedicated to reverse engineering the old Sierra game engines. It's relatively old, but contains, among other things, IDEs for developing games that run under Sierra's AGI and SCI interpreters.
