scrolling graphics set it apart from similar games. A short summary of the trilogy in 1992 by PC World termed it "one of the most spectacular games available" and praised the "superb" sound and graphics, and a similar summary in CQ Amateur Radio described it as "Nintendo comes to the PC" and the "best action/adventure game" the reviewer had ever seen. After its release in December 1991, Goodbye, Galaxy met with sales "about a third" of the original trilogy. Scott Miller of Apogee blamed the falling sales on the lack of a third episode, which he felt undercut the shareware model of the game. Tom Hall has also claimed that the split hurt the sales of the shareware episodes, though he has said that "they still did decently, though". PC Zone, in its first issue in 1993, quoted shareware distributors as saying Goodbye, Galaxy was one of the top shareware sellers of 1992, behind Wolfenstein 3D. IGN has also referred to the pair of episodes as "Apogee's hottest sellers". Hall has claimed "The Armageddon Machine" as the best Commander Keen episode and his favorite. Aliens Ate My Babysitter also did not sell as well as hoped for by id, which the team partially blamed on what they felt was terrible box art done by a company that had previously designed packaging for Lipton tea. Despite this, the sales were strong enough that id agreed to use FormGen as a retail publisher for at least two more games. PC Zone also stated that the sales of Aliens through shareware distributors was one of the highest in the shareware market in 1993. In October 1992, the Shareware Industry Awards gave the Commander Keen series the "Best Entertainment Software and Best Overall" award. A review of the entire Commander Keen series in 1993 by Sandy Petersen in the first "Eye of the Monitor" column for Dragon described the series as action games with "hilarious graphics". Acknowledging its debt to Super Mario Bros., he called it, especially Goodbye, Galaxy, "one of the best games of its type" and praised it for not being "mindlessly hard", instead requiring some thought to play through, and especially for the humor in the graphics and gameplay. According to Steam Spy, as of June 2016 there are approximately 200,000 owners of the 2007 Commander Keen Complete Pack on Steam, and approximately 80,000 owners of the Keen Dreams release. The
