Some 'cyoa harry potter fanfiction' stories focus on alternate timelines. For instance, if Harry had been sorted into Slytherin instead of Gryffindor. In these stories, he might have different friends, different rivalries, and a completely different path in his fight against the Dark Lord. Also, there are stories where he uses time - turners in more creative ways, changing not just his own past but the entire wizarding world's future.

It depends on how you define 'appropriate'. In the context of the mainstream Harry Potter fandom which includes a large number of young fans, 'si harry potter lemon fanfiction' is not appropriate as it likely contains content that is not suitable for younger audiences. However, if we consider it from an adult - only, more niche perspective where people are aware of and okay with adult - themed fan works, then some might consider it appropriate within that very specific context. But overall, given the popularity and family - friendly nature of Harry Potter, it's not appropriate in the general sense.
Another good one could be 'A Cadmean Victory'. This fanfiction stands out for its complex character development. The self - inserted character has to navigate the tricky world of Hogwarts and the wider wizarding world, and the story does a great job of showing that journey.
I'm not entirely sure specifically what 'si harry potter lemon fanfiction' is about. 'Lemon' in fanfiction often refers to stories with sexual or adult - like content, but it's hard to say without actually reading it. However, in the context of Harry Potter, it might be some sort of fan - created story that twists or expands on the original Harry Potter world in ways that might not be in line with the official canon.
One popular trope is the 'alternate universe' where the story takes place in a different setting than the original books. For example, a modern muggle world with a hidden wizarding society. Another is the 'time - travel' trope, which allows characters to go back in time and change events. And the 'found family' trope is also common, where characters form deep bonds outside of their biological families.
There are many 'Harry Potter SI OC fanfiction' stories to explore. For instance, 'The Secret Apprentice' is a story where the OC becomes an apprentice to a powerful but reclusive wizard. It delves into the secrets of magic that are not taught at Hogwarts. Another one is 'The Cursed Necklace' which follows an OC who finds a cursed necklace and has to figure out how to break the curse without getting herself killed. Then there's 'The Outcast Witch' which is about an OC who is shunned by the wizarding community for her different beliefs, but she rises above it all and shows that being different can be a strength.
There are 'Harry Potter Gamer SI Fanfiction' stories that revolve around the SI character using their knowledge of game glitches. In the wizarding world, this could translate to finding loopholes in magic spells or magical laws. They might accidentally discover a way to apparate without a license by using a glitch - like thinking from a game. And also, some stories show the SI character making friends with the original characters by introducing them to fun gaming - like activities, such as a magical version of hide - and - seek that's inspired by a video game they used to play.
Another appealing factor is the freedom it gives to the author. Since it's fanfiction, they can deviate from the established canon quite a bit. They can create a unique story arc for the SI that involves all kinds of dark elements. Maybe the SI has a connection to a dark wizard from the past or discovers a long - forgotten dark spell. This freedom allows for a lot of creativity and makes the stories unpredictable, which is really appealing to readers.
One good example could be 'The Unseen Path' where the Self - Insert (SI) character has to navigate the dark underbelly of the wizarding world. The SI in this fic might have to deal with dark magic in ways that the original characters didn't, adding a new layer of intrigue.
