- Crossdressing Voices: Daxter is voiced by a woman in the Japanese version, making him sound more like a prepubescent boy rather than a teenager like in the English version.
- Follow the Leader: It is by no mere coincidence that Jak II was made considerably darker than its predecessor and was released around the time people would just be finishing up Vice City and needing something to placate their sandboxing fix. The first game is also a blatant Super Mario 64 clone, but it's more forgivable than most due to the game's absolutely exquisite presentation. The transfer from "traditional collectathon platformer" to "action game with some platforming elements" is generally considered justified, as open world steal-car games went from strength to strength in the early 2000s, while character platformers nearly disappeared entirely for the next decade (unless they starred Mario).
- Real-Life Relative: Jak's Japanese voice actor, Shōtarō Morikubo, was actually married to Ashelin's Japanese voice actress, Yū Asakawa, though their marriage ended in divorce after only two years.
- Talking to Himself: Phil La Marr voiced several characters in the games, including Sig, Count Veger, Kaeden and G.T. Blitz / Mizo.
- What Could Have Been: In the Jak X commentary, they say that the original plan was to make Rayn "more Rubenesque" to (sort of) match her father. They decided to go for the "standard" Naughty Dog female model for her, instead.
- Given the implications at the end of the first game, it's not hard to think that Jak II might have been at least considered for a more lighthearted tone like the first game. Of course, if there were any such plans, they were abandoned in favor of a Darker and Edgier sequel that changed a lot.
- Judging by the Concept Art, Bob Rafei was always trying to give Jak dreadlocks, braids or loose ponytails from Jak II on. In Jak X he apparently came very close to having muttonchops.
- Mizo was originally supposed to be a Split Personality, rather than just G.T. Blitz without his disguise. This was dropped because it was deemed too difficult to convey in the specific, short cutscene.
- A 'realistic' reboot was actually considered by Naughty Dog after the completion of Uncharted 3: Drake's Deception. But they opted for The Last of Us instead, realizing both that the fans 'would probably not be pleased', and that they no longer felt any desire to return to the series.
- The Lost Frontier was conceived and started by Naughty Dog. It was originally going to be finished by them as well, but difficulties with the Uncharted project on PS3 (and maybe other problems as well) caused Lost Frontier to be cancelled early in development, and all remaining developers migrate to Uncharted. The final version of the game is a recreation instead of a port, based somewhat on the original script and gameplay ideas, but not what the first planned version of the game would have been. For example, Dark Daxter, despite being an idea kicked around during Jak 3's pre-production, was never meant to be in TLF in any form.
