The story of Ark: Survival Evolved involves players being stranded on an island and facing numerous challenges. You need to tame dinosaurs, build shelters, and form alliances to thrive. There's a sense of adventure and exploration throughout.
Once, my friend was trying to tame a triceratops. He prepared all the right food but accidentally threw the food at himself instead of the dinosaur. The triceratops just stared at him like he was crazy. It was hilarious.
One funny story is when my friend was trying to tame a dodo. He chased it around for ages with berries in his hand. The dodo kept running in circles and finally ran straight into a tree and got stunned. It was so silly looking that we couldn't stop laughing.
The story of Ark: Survival Evolved involves a struggle for survival in a harsh environment. You start alone and must gather resources, form alliances, and battle against both the wild and other players. It's a thrilling adventure with lots of challenges and surprises along the way.
In my Ark experience, there was this time I tried to tame a huge brontosaurus. I thought I had enough narcotics to keep it knocked out. But I miscalculated and it woke up in the middle of the taming process. It was so angry and started stomping around my base. It destroyed half of my fences before I managed to calm it down. Looking back, it was a chaotic and funny event.
Conflict is another major theme. This could be conflict between different species from the two crossovers. Say, if it's a crossover with a alien - invasion type of story, there would be battles between the ark's dinosaurs and the invading aliens. It creates a lot of action and drama in the fanfiction.
Survival is a very common theme. Since the game is about surviving in a harsh environment filled with dangerous creatures, most fan fictions revolve around characters' struggle to stay alive. Another theme is exploration. Writers often send their characters on adventures to discover new areas of the ark world.
One idea could be that the RWBY characters are dropped into the Ark world and have to learn to tame the dinosaurs to fight Grimm that somehow also exist there. For example, Ruby could use her speed to outmaneuver the dinosaurs while taming them.
There are also fanfics that deal with the scientific aspects of the game, like the study of the prehistoric creatures' behaviors. Writers might explore how the dinosaurs interact with each other in a more natural and scientific way, rather than just the typical combat scenarios. This type of fanfic can be both educational and entertaining for fans of the game.
