Stories that focus on the backstories of the Stargate gamer characters can be quite popular. Like exploring how a particular character got into the Stargate gaming world, their initial struggles, and how they overcame challenges. This gives more depth to the characters we see in the game.
Another place could be FanFiction.net. It has been around for a long time and has a dedicated section for Stargate fanfictions. You might need to dig a bit deeper as there are a lot of stories, but it's a good source. There are also some Stargate - specific forums where fans might share their fanfiction works, so it's worth checking those out too.
Teal'c is a very popular character in Stargate the Gamer fanfiction. His unique backstory as a former Jaffa and his combat skills are appealing. Also, Vala Mal Doran is often included. Her roguish and unpredictable nature can bring a lot of chaos and fun to a story. She can be a great foil to the more serious characters. Additionally, General Hammond is sometimes featured, especially when it comes to stories about the SGC's leadership and decision - making.
A plot could involve a gamer who is a master at first - person shooter games. In the Stargate universe, they find themselves in the middle of a battle against the Replicators. Using their quick reflexes and aiming skills from gaming, they start training the SGC teams in new combat techniques. Also, a story where a gamer accidentally hacks into the Stargate control system in the game and this somehow activates a real - life Stargate connection, leading to all sorts of adventures.
First, you need to be really familiar with both universes involved in the crossover. For Stargate, know the different gates, the Goa'uld, and the various teams. Then, come up with an interesting premise. Maybe it's a new enemy that can only be defeated by the combined forces of the two universes in your crossover. Keep the characters true to their original personalities.
A Stargate and Battlestar Galactica crossover can also be amazing. Picture the Stargate teams dealing with the Cylons. The fanfiction often explores how the military strategies from both franchises would clash or blend. It usually has a lot of action - packed scenes as well as some deep character - driven moments.
A possible fanfiction could revolve around a joint mission. The races from Babylon 5 and the teams in the Stargate universe come together to face a common threat. Maybe an ancient evil that has the power to destroy both their worlds. They would have to combine their knowledge and resources, like the Psi Corps abilities from Babylon 5 and the Ancient technology in Stargate.
One idea could be that a Sentinel's enhanced senses are used to detect a hidden Goa'uld base that the Stargate team has been searching for. The Sentinel could sense the unique energy signatures or the presence of the symbiotes in a way the normal technology couldn't. Another idea is to have a Sentinel character be accidentally transported through the Stargate to a different planet. There, they have to use their Sentinel abilities to survive and team up with the Stargate team members who are also on a mission there.
The Ministry of Magic would probably oppose it. They are always concerned about maintaining the secrecy of the wizarding world and a stargate could potentially expose it to non - magical beings or lead to unwanted magical interference from other realms.
In the original Stargate series, Alteran knowledge was more of a background element. However, in 'Stargate Alteran Knowledge Crossover Fanfiction', it becomes the central focus. The fanfiction might introduce crossovers with other fictional universes or concepts, which is not a part of the original series. Also, the fanfiction can play around with the Alteran knowledge timeline, perhaps showing how it could have been used differently in different eras compared to what was shown in the original.
