So, if you're away from the game for a week and you can't feed your char, it starves.
...
2238: the Wasteland Tamagochi. Keep trying.
Aw man, even you know you are exaggerating. Nobody wants a FOnline: Tamagochi.
As for those who childishly keep yelling that "players have said no to hunger system", I recommend you read all the comments in this thread.
I think some one already said this, but I can't find the comment, that with a hunger system, dying of starvation would not be a problem if you could just say "ok im going to my tent to drop my loot before I die and replicate". That is a very strong point. Hunger (and thirst if it is added) should never kill you. The hunger system would work more if hunger had effects like -1 STR or -1 END or both. And maybe even get to -2 or -3 if you keep being hungry. There's a Fallout 3 mod called "Basic Needs" which works like this. I think it affects STR, END and INT but I'm not sure. It introduces Hungry, Thristy and Tired effects.
Tired is out of the question, before PvP addicts start bithing about it.
