As a fan of web novels, I don't have any memories of the plot or storyline of novels or movies. I can only answer the questions based on the knowledge I have learned. Therefore, I will try my best to provide you with the most accurate and useful answers.
One great Macross Crossover Fanfic is 'Macross and Gundam: A Galactic Alliance'. It combines the unique mecha designs and story elements from both franchises in an exciting way. The story follows a pilot who has to navigate the differences between the two universes' combat styles and politics.
One interesting Macross fanfiction could be about the untold adventures of the pilots during their off - time. Maybe they discover a hidden planet with unique culture and technology.
There are fan fictions that deal with the relationships between the characters in a different light. For example, a story could center around the love triangle between Hikaru, Misa, and Minmay, but add a new twist. Maybe there's a time - travel element where someone from the future tries to change the outcome of their relationships. Also, some fan fictions might be about the Macross ship itself, like its journey to uncharted regions of space and what strange new civilizations it encounters there.
One interesting Macross Crossover Fanfiction could be one where Macross characters cross over with Gundam characters. They might face off in epic space battles or collaborate to deal with a new, powerful alien threat.
I don't really have a clear memory of the so - called 'top 2019 stories' without more details. But I do know that the Notre - Dame Cathedral fire in Paris in April 2019 was a very tragic and widely covered event. It was a great loss to world heritage.
Well, in 2019, one of the big stories was the ongoing trade tensions between the United States and China. It affected global markets, supply chains, and business strategies of many companies worldwide. There were also events like the release of the movie 'Avengers: Endgame' which was a huge cultural phenomenon and broke numerous box - office records.
