For those of you that haven’t heard of this video, it is produced by Minute Physics on YouTube and the link is below. This video talks about the ways in which people travel through time and the various methods in which they can change the course of events in a given time stream. It also talks about the various movies and books that employ the plot device of time travel and how realistic it is in terms of Einstein’s theory.
Actions must have consequences in order for the reader to care about the characters. In the case of role-playing games, the players must have concrete rules that govern the multiverse. The rules must be consistent and easy to understand. This is the basis for Logical Consistency. This video explains very well the differing types of time travel. The gentle reader will see that this can be a fun alternative to the “work-a-day” plots and scenarios found in a lot of adventure modules.
Time Dilation is the idea that could be used in most space travel games. Metamorphosis Alpha role-playing game comes to mind, as well as The 77 Lost Worlds RPG. Both games have space going ships and could employ the plot device of Time Dilation. Say, for example, the Warden is traveling at near light speed and it docks with another ship that had previously departed the Warden five years in the past. The second ship may have been trying to find help and enters into a worm-hole. They instantly travel three years to the future. They, much to their surprise, encounter the Warden again. When re-entering the Warden, they find a great disparity in terms of age. The people on the Warden are much older than the folks on the second ship. This can make for great drama.
Time Travel Paradox is another plot device that could be great fun. In this category, we have three subcategories to discuss. Although the three subcategories are not mentioned by name in the video, I believe it to be important to include for the sake of instruction.
Casual Loop A loop is an anomaly of time travel that befalls when a future occasion is the cause of a past occasion, which is the cause of the future event. Note: No origin can be determined.
Grandfather paradox”This occurs when the past is changed. This causes a contradiction and will change the future. The time traveler should do only the things that have been done in the past. See, Back to the Future 2.
Fermi paradox is a type of question that asks: “If time travel is a real thing, where are all the visitors from the future?” The answer is, for games purposes: the time travelers disguise themselves to avoid detection.
The Do Over time travel. In this form, the traveler gets to relive the same segment of time over and over. He or she has the free will to learn from previous mistakes. This is much like a video game. This can be used by benevolent GM’s to save the life of a beloved character or characters. Another example can be that the group can try a different method to overcome the problem.
The Anything Goes time travel. This version allows the traveler to go back or forward in time. He or she can see versions of themselves. Back to The Future is an example.
If A then B time travel. This form is logically consistent. See the video for more information. This can be a very dangerous way to thin the party. Use your noodle Game Masters! The sky is the limit.
Time is fleeting and madness takes its toll. Listen closely
In conclusion, I feel that the video is very well made and presented in a thoughtful way that is easy to understand. I would have liked a more in-depth explanation of the various ways one could travel through time, but I think that was beyond the scope of the video. For the gaming community, this video is a great tool for the imaginative designer to create an unforgettable adventure!
