back to the topic:)
i have no issues with cannibalism in its current form; personally don’t think prion diseases are relevent in terms of gamplay, especially given the number of potential diseases you could get eating wolf, bear, deer and chicken meats, nevermind the less than hygenic food prep practices that come about from harvesting meat with an axe or rock that you bash things to death with, and harvest sulphar and wood with.
that said, i do see a potential issue with getting food from your corpse. potentially this could be resolved by disallowing harvesting of your own body, ie you can loot it still, but hitting it doesn’t yield meat or bones. other players bodies work normally, and other players can harvest yours. this would prevent self eating, but allow buddy eating which is still pretty realistic.
i do see a potential issue with this fix in that person A harvests person B, then just drops the meat for person B to collect or eat. but at least it would prevent a single player from chewing his corpse. might be redundant though if you can still suicide/intentionally die to reset your stamina.
