One common theme is the exploration of their cultural differences. Since Spock is half - Vulcan and Jim is human, their different ways of thinking and behaving often play a big part in the stories. For example, how they deal with emotions - Spock suppressing his while Jim is more open.

There's also 'A New Beginning'. This fanfiction takes a different approach, setting the story in an alternate universe where Jim and Spock meet under different circumstances. It's full of action and adventure, while still maintaining the essence of their relationship.
