This is a cool game. How are people playing it? Do you do it all blind, or do you use details to do searches and try to work out the answers based on what you can research?
Both could be fun but it would be less fun to compare scores against someone doing the other method.
I'm using clues from the photo and making searches on those to narrow down the year and location. The joy in this game, for me, is the detective work. I 100% could not do this blind.
I'm of same mind. Taking clues from architecture, wardrobe, vehicles, flora, apparent climate, even in quality of the image are what make this game fun and interesting to me.
It doesn't hurt when the image contains the name of the place in big bold letters, front and center!
