Adventure! was my go-to pulp RPG for years. Even though it was the first of the Aeon trilogy (Aberrant and Aeon/Trinity being the latter two), it had very little in the way of game meta that so often burdened White Wolf products.
Besides the world history, background information and character creation, there are 3 pulp stories contained within. The first story is “Under the Moon” by Warren Ellis and the two additional shorts (“Dust of Death!” & “The Mystery of Volcano Island”) were written by Greg Stolze
