Have an idea in my head about a sci-fi esque roleplay wherein the characters are captured by <insert evil guys here> and forced to fight in an arena for the amusement of that world's general population. events unfold, **** gets crazy, players band together, fight for freedom etc.
not all players would necesarily work together, however. i was thinking of using an alignment system of sorts and having choices made by players affect the course of the plot rather than everyone just being along for the ride. like for example, players a, b & c manage to make it to an escape pod. evil guys offer player b money and freedom if they sabotage the escape pod so it cant fly away.
it wouldn't just be a whole players awkwardly band together, go through plot point 1, plot point 2 etc. it'd be more sandboxy than that, but still have certain plot points designed to drive it forward. sorry if my explanation sucked... lol, but just gauging interest. it would include you creating your own species of alien, their home planet etc, just for more fun.
