i vote pemmican and hardtack be added, even if they give little nutritional value, they can be something worth making and easily, carried/stored forever....or at least mannnny years
also stats/skills would be cool, nothing major, even if they gained .1 lvl something like double drops, from farming, mining, scavenger (increased chance to not break stuff), better run speed, change to "evade" attacks....again nothing major, maybe a few percent. even if you have to be bitten or hit for thousands of damage to reach max level
