Activision have unexpectedly released a treasure trove of legacy titles on Steam, which were previously only available on GOG. Most of them are classic Sierra adventure games, but they also include Troika's Arcanum: Of Steamworks and Magick Obscura, which was published by Sierra back in the day, as well as all five games in Sierra's own wonderful Quest for Glory series of adventure/RPG hybrids. And yes, that includes both the EGA and VGA versions of Quest for Glory 1. The prices are the same as GOG's - Arcanum for $6 and the Quest for Glory Collection for $10. If you don't already own them on GOG, or if you're obsessive about your Steam game collection, these games come highly recommended. I wonder if these releases bode anything for the future of Activision's ill-fated nu-Sierra initiative.
