* HarsherInHindsight: Most of the established alien races in ''SG-1'' are left unmentioned in ''Infinity''. While most likely due to ''Infinity''[='=]s creative team being unfamiliar with them, the final episode of ''SG-1'' shows that [[spoiler:the Asgard would not have lived to ''Infinity''[='=]s time anyway, having committed mass-suicide by destroying their home planet, in order to prevent the Ori from acquiring their advanced technology.]]
* HilariousInHindsight:
** The Goa'uld System Lords were defeated within the last thirty years before the start of ''Stargate Infinity''. ''Series/StargateSG1'' was in its sixth season at the time ''Infinity'' premiered, during which a new BigBad came into power and the System Lords' power gradually began to crumble away. The System Lords were officially defeated in Season 8, and the last remaining one was killed in the GrandFinale movie, ''Film/StargateContinuum''.
** The Stargate program was at some point made public thirty years prior as well. [[WhatCouldHaveBeen Though it was canceled]], this would have happened in the third SG-1 movie, ''Stargate: Revolution''.
* PainfulRhyme: The [[https://www.youtube.com/watch?v=67E-_SQLVRo theme song]] does not contain a ''single'' true rhyme:
-->Built by Ancients so long ago,\\
The Stargate lay 'til we broke the code,\\
Now it takes us through the universe\\
On our mission to get back to Earth.\\
\\
We are hunted and on the run,\\
And together we overcome,\\
Fighting evil through the galaxy:\\
Stagate Infinity!
