Way back in 1987, aside from an ill-fated dalliance with the original Traveller (my character died during character creation), I’d only played sword and sorcery rpgs. A friend of mine borrowed a set of Gamma World from an older kid and we had a go. I don’t recall if we got much further than character creation but I recall at the time being impressed by how much stuff there was in the box set.
Is this the whole set? Were there dice? Anyway, it’s still a lot of stuff, the map is pretty impressive, and there’s a pre-generated tree character to boot!
EDIT: reading the back of the box tells be there should be 2d10 and 4d6.
