Although Keen Dreams wasn’t the breakaway success for John Carmack and the rest of id Software the original trilogy of Commander Keen games managed to be, they did wind up crafting a superior engine in the process of developing it. With Keen Dreams having been completed by June of 1991, id began work on a new trilogy of Commander Keen episodes to be named Goodbye, Galaxy. The team intended for the episodes to be published in the same manner as the original trilogy. Players could order the episodes individually or all three with a lump sum totaling less.
The following August, Mr. Carmack and his team had completed a beta version of the series’ fourth official episode: Secret of the Oracle. Fellow programmer John Romero sent it to Mark Rein, a fan that he had met from Canada who offered to playtest the game. Mr. Romero was then surprised when Mr. Rein sent back a large list of bugs he compiled. Coupled with his impressive business acumen, Mr. Romero proposed hiring him as a probationary president in an attempt to expand their business. Within weeks, Mr. Rein made a deal to get id into the commercial market, but there was a catch. The sixth episode was to be made a standalone game, published as a retail title through the company FormGen as opposed to id’s signature shareware model. The fledgling company signed the deal, although Scott Miller, an employee from publisher Apogee was dismayed, believing reducing Goodbye, Galaxy to a duology would hurt sales.
In the same month, the team moved from Shreveport, Louisiana to Designer Tom Hall’s hometown of Madison, Wisconsin. Working out of a three-bedroom apartment, they worked on the Goodbye, Galaxy duology, any remaining Softdisk projects, and the now-standalone sixth Commander Keen installment. One software catalog listed the release date in September of 1991, but the project ended up being delayed. The sixth episode, being a standalone effort, was developed after the fourth, but before the fifth. The fifth itself would be created in less than one month.
All three games would see their release in December of 1991. As Mr. Miller predicted, the sales figures of Goodbye, Galaxy were roughly one-third those of the original trilogy, which had made $20,000 in its first two weeks and $60,000 a month by June of 1991. Mr. Hall himself would also blame the falling sales on the lack of a third episode, which undercut their shareware model. Nonetheless, the games still fared well overall, becoming one of the top shareware sellers of 1992. Like the original trilogy, the two games that formed the Goodbye, Galaxy duology, Secret of the Oracle and The Armageddon Machine, were well-received. As the first installment of this duology, does Secret of the Oracle mark a significant improvement over its four predecessors?
