There is one thing I wished... something I wished for over 15yrs for Shenmue. I want Yu Suzuki to increase the value of buying drinks and eating food. If Ryo is always well hydrated and eats appropriately (on time) then everything he does will always be on top form. However, if you eat and drink at inappropriate times or even hardly ever eat or drink at all, you will see Ryo always fatigue and his attacks and defense will be weaker than before. He will never go below or above a certain threshold, the whole point is to make Ryo feel more "alive" and to give you a stronger reason to use all those awesome vending machines, restaurants and so on. Yes, you noticed that I didn't mention a HUD for this, well, it's because you don't need it because Ryo's body language well do all the talking. To go a little deeper without going too deep, you can let everything be leveled by the amount and quality level of the food which will help make more distinction between eating food from a restaurant to one from a small shop or vending machine. The other domino effect of this would mean that you NEED to make money and make sure you have money in your pockets, which will domino effect further into money management. This is what I'd love for there to be in Shenmue. It would be fantastic...
I could see people hating something like that, but I would love that. It sounds sort of similar to how Snake Eater worked, albeit more focused on offense than defense. Considering Shenmue III takes place in rural china, it would be neat to have to actually hunt for food from time to time at some point. Like spend a period of the game focusing on surviving in the wilderness - building shelter, hunting, etc. I don't know if the story necessarily calls for that, though.
