Whoa, deja vu. I'm not going to claim the current food/health/stamina/hunger system is perfect(I am a big fan of it), but I think it is wrong to restrict design to systems that instantly clear to all players, as if such a thing exists. Seriously, what's the problem with short journal entries? You guys are starting to make me feel like a codger thinking, 'why can't these damn kids just read a bit?'
The things that might seem 'intuitive' could also just be familiar and learned, not a priori. How are you supposed to make something cool and new? not just a copy of every other game system simply because people will get it without complaining. The Internet is always there for players to ask others simple questions if needed. I know I've seen some ridiculous ♥♥♥♥ asked about other games and thinking, "how did they not understand that?"
