- Development Gag:
- The Planet Killers from the last mission in Homeworld 2, which even the characters express confusion on what they are or where they came from and can only be damaged by the most powerful ships in the game, are the design for the T-Mat ships intended for the first game. The Council ship that appears at the very end of Homeworld 1 was a later design for the same race that was created after they realized the engine couldn't handle the first design. They would have been a mysterious race (potentially a Bigger Bad) so much more powerful than you that all you could do was get out of their way.
- The hyperspace gate network that appears with no buildup at the end of 2 was apparently a callback to the version of the game originally teased, Homeworld: Empire, which had a completely different plot and apparently revolved heavily around such a network.
- Executive Meddling: Gearbox and GOG released Homeworld: Cataclysm as Homeworld: Emergence, due to the word "Cataclysm" is now trademarked by Blizzard Entertainment for World Of Warcraft: Cataclysm.
- Fan Nickname: "Banana Ship". Guess what it is for.
- Keep Circulating the Tapes: Sorta. The main reason why Gearbox didn't remaster Cataclysm like they did with the other games is because Barking Dog Studios, the team who made the game, lost the source code and back-engineering it from a retail copy would take years. There's also the fact that BDS are now owned by Rockstar, raising licensing issues as well. It was ultimately released without remaster as Homeworld: Emergence.
- The Other Darrin: Fans were somewhat miffed when Karan S'Jet ended up voiced by a different voice actor in Homeworld 2. During the showcase of the Remastered Edition in 2014 however, the dev team divulged that they did ask Heidi Ernest (the original VA) to reprise her role and even brought her into the recording studio. Problem is, she was nine months pregnant at the time and her voice wasn't quite the same, so the team was forced to look for someone else. They ended up bringing Heidi back anyways for the Remastered Edition, both for the first game and the second.
- What Could Have Been:
- The first game was originally pitched as an adaptation of Battlestar Galactica (1978), but they were unable to secure the rights for it. Interestingly, the Darker and Edgier tone planned for it would have pre-dated the later reboot of the series.
- Prominent space RTS developers Stardock and Paradox attempted to obtain the Homeworld rights when they were auctioned off during the collapse of (old) THQ, but were outbid by Gearbox.
