But as with most games where ships and travel are a major feature, Spelljammer campaigns tend to suffer the same pitfalls as a scifi game, or even a mundane nautical-based one. Specifically, how do you get each individual player an active role when there are only a limited number of actions to take aboard a single vehicle? Ship battles sound like fun, if everyone had their own ship to control. But there is usually only one person at the helm and one pilot to drive it. Everybody else takes secondary (or tertiary) roles either assisting someone else in their primary roles, damage control, or operating a single artillery weapon. That is at least until a boarding action is executed and then it turns into a regular D&D skirmish where normal battlefield roles are resumed.
