Realism is SHIT most of times. Imagine your character crafting, building something, then he must stop for urinate or poo. Very, very funny (sarcasm). Or even better (worse), you must make a check or get depression, fail the check and you cannot do anything.
Realism is great a lot of times, is why there are so many survival modes for different games. Bodily functions are already in another game I play, SCUM. This is not a pain at all, you just have to remember to go like in rl before you do something important. Mental states may very well be added before release, there will soon be a better metabolism and injury system than the current one.
