That's only a matter of definition then. You define a fantasy world as created upon the real world, I define a fantasy world - at least one like TES - to be unique and only assume normal physical laws to apply where nothing else has been stated because otherwise the game world would be completely unpredictable and thus the game unplayable.
But that's just juggling with words, really. Be it realism, believability, immersion, simulationism, logic or whatever names there exist for it, it needs to be there.
Again your wrong:
TES IS a fantasy world, but from day one, magica apart, and in ANY other fantasy game but awfully bad JRPG (all of them, can t for the damn of it play them), you are in LSD and cocaine filled mind full of i win buttons.
Since there s a HUMAN race, and there s HEARTHLY fisics, the rest should apply as long as it viable.
Your just trying to justify your unwillingness to have a plausible world.
Fantasy not mean impossible, unlausible world.
Fantasy is the definition of a portian of reality that isn t like our real world.
It has nothing to do with anything unexplained stuff it or leave it.
Bethesda trought all its TES implementation has meant a plausible world (not including failure to implement it right) and that is its strenght.
What you calling for is a simplistic gameplay while most people want a plausible gameplay containing advanced features.
In the end of the day this discussion is Beth fault. As many games allow the player to tailor part of the games as they see fit on SP and MP
This could include eating sleeping etc...
And bethesda is lagging behind, even thought if its their strategy to let most of it to the modders.
The right approach would be checkers like:
Activate limited stamina on:
Walking
Running
Sprinting
Battling
Activate sleep deprivation :
Activate eat drink deprivation:
Show compass:
Show quest place indicator:
Show health bar on hud
...
...
All those are very simple to do and implement on their basic lvl which is what all players want. (to be able to choose) and leaving more complex iterations for modders for example.
