Each has its own rules for characters, travel, and paradoxes. A detailed discussion of the paradoxes you should consider in creating your own time-travel campaign. Is meddling with history easy? Impossible? Or just a Very Bad Idea? Parallel worlds . . . "what if" dimensions where something, or everything, is different.
