LOL at this thread. Reminds me of the dawn of computing power.
"Hey guis, wouldn't it be cool if the map had more than just monsters and NPCs, like, I don't know, horses and cows?"
"Hey guis, wouldn't it be cool if we can kill those horses and cows?"
"Hey guis, wouldn't it be cool if we can bbq the meat from those horses and cows?"
"Hey guis, wouldn't it be cool if our heroes can eat bbq?"
"Hey guis, wouldn't it be cool if our heroes got hungry so they have to hunt? I mean, why give us the ability to kill horses and cows if our heroes never had to eat?"
"Hey guis, wouldn't it be cool if our heroes had to poop? I mean, all that food have to go somewhere right? Why don't we make it so that you have to go sleep at an inn to poop, and if you don't poop for a long time, you start to lose health?"
"TOTALLY RAD!"
...or not. I don't know about the poop part, but the rest of it actually happened (along with "hey guis wouldn't it be cool if your equipment wore down and then broke down").
Megalomania total control/real life simulation (LOL, why do I want to simulate real life? I have my own) sounds fun until it gets implemented, and then you realize it's just tedium.
