Naturally the words realistic, plausible and believable, refer to different concepts, on different levels but may include the same thing.
That is the reason that i used this three words and not just realistic.
To define realistic i have to provide the definition also for real and realism.
Real means in the matter something that exist, and therefore a part of our universe.
Realism besides being a direction of philosophy and arts, means a correct and appropriate estimation of reality. (Or derived out of something real, through means of abstraction.)
Realistic means oriented on the reality (not necessary from reality but not contradictory to the reality), or on realism if we talk about art direction.
There you see why i used the word realistic and not realism.
Now to answer my own first question to you: The last two Batman films, i did not like that the Gotham City was so realistic. Batman needs a appropriate stage, and a realistic city is not the stage for him, he didn't fit in.
Then on the other side everything else was quite implausible. So as you see my first question, a yes answer was possible, but mostly implausible.
Now back to the three words: realitic, plausible and believable.
Something may be realistic, plausible and therefore for all people believable.
Something may be impossible therefore total unrealistic, and then it is for a sound mind the believe about it is impossible. (Religions are that kind of things or Superman.)
Realistic things can be compared on this dimension, plausiblitiy (as likely or apparently valid) of a event is measured in the stochastic with a probability value and this can be compared. The level of belive can be also a scaled.
Something is more realistic, if the probability of this construct is higher, therefore more believable, than something with lesser probability.
To the witcher.
I have tried today something out: how many weapons can i wear on myself. So i put on my post apocalyptic survival gear on. I am not a cosplayer, i am an eccentric that believes, that mankind will blow them self in near future out.
2 long machetes (belt and thigh mounted) , 2 Glock daggers (Boots over the shafts), 1 foldet hand crossbow (belt and thigh mounted over the machete), 6 throwing knifes in a poach on the mole west and still many space left on the west.
Rücksack mole system: 2 Bokken as a substitute for a long barrel firearm, 1 Shinai, 1 Ken, 1 Warhammer. And 1 crossbow in my hands. My main concern is more about the weight, because with the bullet resistant west it all gets quite heavy.
Then i run out of weapons and still got space left in the Rücksack and on the mole west. I had to use my Kendo and Jaido training equipment as a substitute for the firearms, becase i do not own any firearms due to my residence.
Don't get me wrong i love the witcher, because in a way i was like him. Sex, drugs and Rock'n Roll. The story is very good. But mostly because the world is very mature and the problems (racism, etc ) are realisic, beside the magic and monsters.
As you see that the realisc things of the witcher is not an issue, but the highest value of the game, and the books. His equipment value is made for travel and to be fast, but as you have seen one person can carry much much more.

In the case of Inquisitor you even need to fight respawned enemies to get your old loot to the shop. I'm doing this kind of roundtrips only in games in which every penny is needed (for training for example) not out of greed.
In the case of Inquisitor, it has to be really tiresome. I had only once the necessity to do this: in Fallout 2, to get a SMG (first good weapon), to kill the slavers. In FO:3 i have done this to give every trade caravan member the best armor, to give everyone water, and to have full shelves. In FO:NV i have done this, so have a superb equipped depot. In no other game i have done this so consequent. But i think that it is not a problem resulting from a to small and limited backpack, but more a game balance one.
Many people believe in a false dichotomy: realism and fun standing partitioned form each other, and you can choose only one of them. Or that a too high form of realism costs fun, that would mean also that a higher form of abstraction or unrealistic things make more fun. But this can be quite the opposite, if we are honest. The only problem with more realism or more realistic systems are that the degree of micromanagement can get higher. As you see i have wrote "can get higher" this means not necessary that it will get higher, there are always solutions to counter this additional work. I have proposed for the combat mechanisms in Wasteland 2 a script option menu, besides that character sheet and inventory, where you can edit the specific combat behavior of one ranger.
