How would the map work? Do you walk around a very large area split up into smaller areas sort of like in the water plant, or would it sort of work like in Fallout 1 and 2 where the map zooms out and you travel through regions?
Also I'm thinking of writing about some sort of abandoned theme park, along the lines of a small Disney land, with animatronics and stuff. Maybe robot bunnies? I unno, but it'll be fun to write. Not sure how hard it'd be for the coders, but how hard would it be to add minigames of sorts?
