As I was saying last week, some Twitter accounts are of particular value to GameMasters because they can inspire some pretty cool adventure ideas for their favorite role-playing games. And for me, that means time travel games like the Doctor Who RPG and GURPS Time Travel (though I also expect good things from TimeWatch, a Kickstarter I've backed). Time travel at least partially feeds on history, and so I recommend following History in Picture (@HistoryinPics) which posts evocative and often little-known and unusual images from human history. The more straightforward stuff fits strictly scientific takes on the genre, while the unusual can yield science-fiction adventure seeds for more loosey-goosey stuff like Whovian gaming. Let's look at a few to see what they inspire.
Any other time travel (or historical) gaming fans in the house?
