Adored by the Network: Infogrames Europe had a strange fondness for four of the games (Putt-Putt Enters the Race, Spy Fox 2, Freddi Fish 4, and Pajama Sam 3), often given the Fan Nickname "the Infogrammes Four". Whenever they were ready to lead foreign dubs of Humongous games, these four were usually the first in line to get dubbed, like in Italy and the UK.
Dueling Dubs: Russia had at least 6 different companies translating the games into Russian, three being bootleggers (Fargus Multimedia, 7Wolf, and Vector) and three being official (Akella, Russobit, and Boolat). Fargus Multimedia actually managed to dub more games than the three official dubbers did COMBINED.
Executive Meddling: Not much during their early years, but after they went under Infogrames' ownership, this happened in spades. According to some of the former workers, they were very resistant to any new intellectual properties, including one case mentioned below. They also were responsible for a lot of the reasons MoonBase Commander failed, showing a complete lack of interest in it and going so far as not giving it an E3 press release. Ron Gilbert held such a disdain for them that he attempted buying his company back from Infogrames, but the Internet bubble popped the day the purchase was supposed to happen; understandably, he and many other key members, including Dave Grossman and Shelley Day, left after realizing things weren't going to get any better.
Fan Nickname: Well, more so "staff nickname", but it's common for former employees of the company to refer to each other as "Humongoids".
Hey, It's That Sound!: Humongous recycled a lot of sound effects in their games, many of which originated from sound effect libraries.
Keep Circulating the Tapes: Humongous generally tried to avoid this, since they kept repackaging and re-releasing a lot of the games and putting them back on the store shelves. Putt-Putt Saves the Zoo alone was repackaged so many times that it's become remarkably easy to find.
On the old section for demo downloads on the site, it once said "Warning: These files are HUGE! (5 to 24 MB)"
When the games were first released, 640 x 480 was considered high resolution and the games fell under Genius Programming. In hindsight, that doesn't say much due to how far they pushed the SCUMM engine to its limits.
There exists conceptual designs for 3D models of the Junior Adventure characters as well as a 3D background for a Freddi Fish game that never saw the light of day, meaning the games were about to head into the 3D direction before the Atari buyout.
