if he didn't go to school yet, how would he know what's different?

Honestly that's a valid point too. He can start with it. Then use the code library to build the rest of the functionalities

well for starters, you get a dimensional space hidden from anyone which can be used for smuggling, transportation etc Which by itself could boost you compared to others. Now you have other powers on top of that. you get the point. It suddenly makes you have that much more power than others.

that is actually logical. But it can be taken as source and modified into something else entirely and depending on hardware, be common source code for all drones. Think of it as an enhanced drone code. This is because sections of it can be reused for other drones later, instead of coding the entire thing again.

Even then, just physically he is stronger than most people would ever be in GOT. And if he has skills to support his physique, then he would be unbeatable in combat

Don't put inventory on him. It just ruins immersion. Him being strong just means he can carry that much more load on him. If you give inventory on top of that, that's way overpowered. He is a space Marine for heaven's sake

inventory itself is overrated. it shouldn't exist in the first place. bypass weight restrictions using other ways.

it would have been better to say, previous generations did learn the language and he got the memory

But jinchuriki thing leaked and was kept only on the inner circle of the village if you think about it. That's the wierd point. No spy got to know about this information. That's something Sarutobi would have interfered in.

Main reason why sarutobi kept quite about the parent thing was because of the jinchuriki thing. He could have become a target to other village if that information was leaked or was confirmed. Now think that Kushina is the only one who could have become a jinchuriki due to her chakra. If it was known who his parents were he would become obvious target since there was a high chance of him being a jinchuriki. Also it's difficult to keep kids quite about secrets since they can easily be cheated. It was better if third kept him at a distance since otherwise it would have been obvious who he was.

bid farewell is the right word. might be grammar error

yeah

hiruzen just maintained the balance in village even if he had to be the evil one. But Sanzo doesn't care about anything. He doesn't have anything to lose while hiruzen cared about the village atleast in memory. He always had the village as an memory so he doesn't want it to self destruct. You should be scared of Danzo because that guy is bad news.

madara before rinnegan might be a possibility as he and hashirama are equal. And I would say shanks is at the same level at the time

As I understand witches in witcher can't have kids. so make it so that the husband is ordinary and he is reborn with the knowledge of skills of assasins and he trains to get them ingrained in muscle. also make his adopted mother marry a normal human since she is kind of new witch so is not famous. That should solve the problem of story messing around.

drove away ????

instead of stat improvements I think it would be appropriate to indicate who the superior is in an army

not wander, wonder

NPC? I would just say fishing village. he doesn't know if he is in the game

I would use fire power here
