That's the problem with a full team, they are expensive to take care of. I don't know how trainers care that much food for themselves and their Pokémon plus other supplies.
I love hyper-engineered game features. I want a full hunger, thirst, mood, wildness, attachment, happiness, height, weight, training, diet, wants, needs system in Pokemon.
Yeah that would be great pokewilds has some of the things I want. But it has to be done right or else you have a character constantly eating and drinking. That happened to me in skyrim, I was always eating and sleeping.
