I’ve played so many great games, it’s hard to pick just one that I would play again if I could. Actually, it’s not that difficult, since I like pulp and dinosaurs, there’s only one option: Hollow Earth Expedition.
It uses a dice pool system, but to determine success or failure, you only need to count how many dice come up with an even number. It’s a very fast playing system, and while the default setting is the Hollow Earth, the world beneath our world, there are sourcebooks to explore mysteries on the surface world, as well as on Mars. Plus, since it’s pulp and takes place in the late 1930s and early 1940s, the most socially acceptable targets are always there for a good punching, shooting, or dinosaur stampede: Nazis. You can never go wrong fighting Nazis.
