Which of these is NOT a Humongous Entertainment game franchise?
Explanation
The answer is Commander Keen. Commander Keen is not a Humongous Entertainment game franchise because it was actually developed by id Software and published by Apogee Software. Although Humongous Entertainment was known for its iconic adventure games such as Putt-Putt, Freddi Fish, and Pajama Sam, Commander Keen belonged to a separate series created by a different studio. Therefore, it does not fall under the Humongous Entertainment game franchise.
