C’mon… Zombie child inclusion broke this barrier down, so lets go all the way… Any apocalyptic cataclysm isn’t pretty, and the hard realities make it so. I cannot say “make it so” without thinking about Picard, but that’s beside the point!
I feel like the inclusion of the elderly and infants would enrich the (creatively implied) storytelling… Elderly of course would be easier to kill and fairly slow. Infant zombies wouldn’t even be able to crawl, but would bite anything in its range and cause a worse morality penalty than child zombs… (I also keep thinking about a 10% chance for an infant zombie to tumble out of any blanket you pick up…) I even thought so far as dead non-zombified infants, and how simply laying eyes on them would cause a sadness penalty… It’d also allow some new buildings, like daycare and retirement home (two creepy settings in any zombie plague…).
BUT! I’m sure some people would balk at the idea… I can think of numerous stories and movies and games that have crossed this boundary to great effect, and I can’t see why it’d be any different in Cataclysm… So lets hear it! Balk, agree, disagree, do things!
