I want to see changes to hunger mechanic in game but not changes proposed here.
One problem we have here - hunger system is really disbalanced. Easiest sources of food are stomafillia and cooked lizards indeed. +Most of my characters are able to stay alive eating just corpses. Other sources are both rare, heavy and as satiating as above.
I would propose the following nerfs:
1) eating too much of the same food could really cause vomiting, if tried more minor sickness and finally PC could just refuse to eat this again unless he is starving. Nice race/class tweeks could be included too, e.g. trolls and orcs surely should ignore this penalty for lizards.
2) Increase chances to get stomacempia from farming to, say, 90% and make it harder to identify.
3) Cap number of cooked lizards for traders to, say, 15.
4) Reduce satiation from cooked lizards (well, for all, except ratlings).
5) I really would like to see hunger more challenging so would like more negative effects from raw corpses. Especially rotten corpses. Low chance of vomiting, minor sickness... (again trolls, orcs, barbarians are exceptions).
Still above sources are the best.
Hence buffs to other sources:
1) Just make other food junk more satiating. And some of it at least a bit more common. I rarely eat cakes, sauseges, frog legs, melons, almost never apples...
2) Reduce ration weights 4-5 times. No kidding. 100/200s is 5/10kg which seems insenely huge. How one could eat 3-4 such rations in a time!? But, yes, keep original satiation value.
3) Buff cooking. Lets imagine that PC's are butchering corpses before cooking. So cooked corpses should weight less - from 90% to, say 30% when cooking is maxed.
For those who don't wanna deal with hunger and feel like it shouldn't play any role in game and cause deaths: turn it off. Shouldn't ADOM have difficulty settings now? Don't know myself since I missed crowd funding... :/
