- Harsher in Hindsight: 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 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.
- Hilarious in Hindsight:
- The Goa'uld System Lords were defeated within the last thirty years before the start of Stargate Infinity. Stargate SG-1 was in its sixth season at the time Infinity premiered, during which a new Big Bad 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 Grand Finale movie, Stargate Continuum.
- The Stargate program was at some point made public thirty years prior as well. Though it was canceled, this would have happened in the third SG-1 movie, Stargate: Revolution.
- Painful Rhyme: The 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:
