Here are some other options, depending on the context:
* "drôle" (funny, humorous)
* "divertissant" (entertaining)
* "plaisant" (pleasant, enjoyable)
* "agréable" (agreeable, enjoyable)
It's important to note that French often uses more descriptive phrases than English for "fun." For example, you could say:
* "C'est tellement amusant!" (It's so fun!)
* "On s'est bien amusés." (We had fun.)
* "J'ai passé un moment agréable." (I had a pleasant time.)
The best way to choose the right word or phrase is to consider the specific situation and what you want to convey.
