There are quite a few out there. Some focus on the comical aspects of a Ranma 1/2 and Yoki crossover. For example, the fanfic where Ranma accidentally gets involved in Yoki's family drama and his attempts to get out of it using his martial arts skills and shape - changing abilities. Others might explore a more serious plot, like when they team up to face a common enemy that threatens both their worlds.
One common trope is the 'fish - out - of - water' scenario. For example, when Ranma ends up in Yoki's world and has to adapt to new rules and cultures. Another is the 'team - up - against - a - common - enemy' trope. It's always exciting to see how their different abilities come together to defeat a powerful foe. And of course, the 'romantic - subplot' where there might be some sort of love interest developing between characters from the two different franchises.
Overall, the FMA manga set is quite complete. It includes all the major plot points and character developments. However, there might be some minor variations depending on the edition or printing.
The unique characters and their humorous interactions in fma comics often bring the laughs. The unexpected plot twists and comical situations also contribute to the fun.
I'm not entirely sure specifically about 'fma visual novel' as there could be many visual novels with that name or abbreviation. It might be related to the 'Fullmetal Alchemist' (FMA) series, in which case it could be a visual novel that tells a story within that universe, perhaps exploring different storylines or character relationships from the original anime or manga.
I'm not sure specifically if there is a publicly available 'fma riza pregnant fanfic'. You could try searching on some fanfiction websites like Archive of Our Own or FanFiction.net.
The FMA manga ended with a powerful conclusion. All the loose ends were tied up, and the characters' journeys came to a meaningful conclusion. It left fans with a mix of emotions - happiness for the characters' growth and a bit of sadness to say goodbye.
