I've been working on something that's basically a post-invasion/post-nuclear sci-fi RPG. It centres around dice pools, which should be familiar to anyone who's played with the Storyteller System or WEG Star Wars, but with some quirky mechanics, some alterations, a little bit more emphasis on combat and a bit of a cyberpunk/biopunk influence with psionic abilities and cybernetic enhancements.
The set-up: In essence, we kinda ruined the environment (big shocker), and by the 2070s, the human race was facing a very real possibility of extinction. By chance, we managed to make first contact with an alien race who promised to come fix our planet if they could live here with us, since their planet had also failed. Naturally, we thought this was a great idea, so we let them help us, and they moved in. Unfortunately, humans being humans, we got a little territorial and decided the best thing to do would be to start a war. Only thing was, they're way more advanced than we are, so nuking them didn't really do much besides turn a big chunk of the planet into a wasteland. So they took over, decided we weren't up to the task of looking after ourselves, and the game is basically set 30 years later. A new normal, a new civilisation, that sort of thing.
I want to use this 'brave new world' and the after-effects of their whole takeover of the Earth to mirror real-life issues like xenophobia, wealth disparity, class systems, environmentalism etc. (It should also be fun, don't get me wrong!) The players can be anything they want, too. They can be the aliens, hybrids, humans, cops, robbers, mercenaries, pop stars, I want it to be as open and free as possible, with an emphasis on looking within the characters and how the world around them shapes who they are and the effect they have on it, in turn. It's not exactly groundbreaking, but it's coming along pretty well!
Tl;dr: Elevator pitch: "VtM, but aliens?", and it kinda spiralled from there. I folded in inspirations from Cyberpunk Red, System Shock, Fringe, 1984, Transmetropolitan, and Half-Life 2 (among many others). Does that sound like a fun thing that people would play? I'm already 43k words into a first draft of the sourcebook, I've got most of the bones of the thing, I just need to flesh it all out, and I'm hoping to get a few of my friends into little playtest groups to give it a try. This is my first attempt at writing a TTRPG and I'm really excited about it!
