Okay so.. after a few months absence I decided to give it another go writing a novel. The first time I tried a sci-fi/fantasy hybrid and soon realised it would be difficult.. so this time around I've gone for a much more traditional genre, that of a post-apocalyptic setting. The only problem I'm faced with is thinking of what caused the apocalypse.. I don't want to go with the 'nuclear war' idea, it's far too overused. But at the same time I want it to resemble that of a nuclear war, as in the world is practically a wasteland, with lots of destroyed buildings, mountains of rubble, factions roaming the wasteland.. etc. I use the Xbox 360 game Fallout 3 as a huge inspiration, but that game related to a nuclear war, so unfortunately I can't totally rip it off. So I guess what I'm asking is.. what could the disaster of been? I want it to be mysterious for the first half of the book, unknown to the population.. then it will be suddenly revealed, but at the same time I don't want it to seem almost fantasy-like e.g. aliens thrown rocks down from space or the god punished the world by blowing **** up. Do you people have any bright ideas? thanks in advance!
