Answer 1

to put simply, one is simulating a game, other is like simulating a game running another game.you can think it as writing a book.

when someone asks you to write a book, it is hard. but **imagine you are asked to write a book where your main character writes a russian book**.

so now you have to deal with another story embedded inside your story and it is also in a language you don’t know and it takes longer because you keep checking the dictionary.
