The food system in Valheim was the best I've ever seen. It isn't really survival, you don't have to eat to stay alive, but it gives you significant enough buffs that it is basically required for anything past the easiest fights. But your character is basically functional without food (you can walk around your base and do stuff; you won't, like, slowly die).

Too many "realistic" food systems feel like a tedious system to be engaged with just to avoid punishment. This somehow feels more like a reward.
