Some fan fictions might focus on the backstories of the other characters. Like exploring what made Ming, Mei's mother, the way she is. It could be that there are untold stories from her own childhood that influenced how she raised Mei, and fan fiction gives an opportunity to dig into those.
One interesting concept could be exploring different relationships between the characters in more depth. For example, the friendship between Mei and her friends could be developed further, like showing their adventures outside of the movie's main plot.
Well, in Red Queen fan fiction, a common concept is character backstories. Writers often expand on the pasts of characters like Maven. They might create a backstory where Maven was not always so easily influenced by his mother, but had some moments of resistance. Another aspect is world - building. Some fan fictions might add new regions to the existing world of Red Queen, with their own unique cultures and power dynamics. And then there's the concept of time - travel in some fan fictions, which allows characters to go back and change key events in the story.
One interesting concept could be the exploration of uncharted regions in Morrowind that were only hinted at in the original game. Fan fiction might describe these areas in great detail, like hidden underground caverns filled with ancient Dwemer machinery. Another concept could be the backstories of minor characters, giving them more depth and significance. For example, a fanfic could focus on the life of a common Redguard fisherman in Morrowind and how the events of the game world impact him.
One interesting concept is the exploration of new Titan models. Fan fiction often imagines Titans with unique abilities or designs. For example, a Titan with the power to cloak itself and its pilot, allowing for stealthy attacks. Another concept could be different backstories for the Pilots. Maybe a Pilot who was once a criminal but is now fighting for redemption in the Titanfall battles. There are also ideas about new game modes within the Titanfall universe in fan fiction, like a survival mode where Pilots have to fend off waves of enemy Titans and infantry without any reinforcements.
One interesting concept could be alternate endings for the game's story. Maybe in the fan fiction, the main character makes different choices that lead to a completely new outcome for Rapture. Another concept could be exploring the backstories of minor characters in more depth, like the splicers, and how they came to be in their current state.
One interesting concept could be alternate character backstories. For example, in Apocrypha fan fiction, a writer might explore what led a minor character to have the motives they do in the original work. This can add depth to the overall narrative.
One interesting concept could be alternative universes. For example, a DWP fan fiction might explore what would happen if the main characters had different powers or origins. Another concept could be character relationships. Writers might develop deeper friendships or unexpected romances between characters that are not as emphasized in the original DWP. Also, time - travel is a popular concept. It can be used to change past events in the DWP world and see how it affects the overall story and characters.
One interesting concept could be the discovery of new supernatural abilities. For example, a character might find they can control time in a unique way that's different from the usual time - control tropes. Another could be the discovery of a hidden supernatural realm that has its own set of rules and creatures.
One interesting concept could be alternate universes where the characters have different fates. For example, Mal could have become a successful Alliance officer instead of a rebel. Another might be relationships that develop differently, like a deeper romantic connection between Kaylee and Simon earlier in the story. And then there are concepts where new characters are introduced that change the whole dynamic of the Serenity crew.
One interesting concept is alternate universe scenarios. For example, what if Kerbal Space Program had a more advanced tech tree from the start? Another is the creation of unique Kerbal characters with their own backstories and personalities. Some fan fictions also explore different planetary systems with strange and exotic planets that are not in the original game.
One interesting concept could be exploring the backstories of the Whos in more detail. For example, how they built their unique houses or what their family traditions are.
