My group was looking for a new system recently, and someone proposed Savage Worlds. Since we were thinking of a sci-fi setting, I proposed Apocalypse World since I was under the impression that was basically a post-apocalyptic version of Savage Worlds. Someone else said no, it was significantly different, but neither of us knew for sure and we didn't have any books for either yet, so we were left wondering.
What's different between Savage Worlds & Apocalypse World, and what's the same? Or are they so different that any similarities are largely coincidence?
