even though i am too young to have lived through that era of gaming i still got some taste through my gba and from playing at friends houses and i have to agree with almost all of them except the one about challenge and the arcades, i think these two were kinda "interconnected" and in the beginning of home consoles it passed over to them too, arcades had to be very difficult cause they didn't have much else to offer and you had the added feature that you had to use coins or tokens bought with coins to play them so if you lost regularly it would be profitable for the arcade store etc
but yeah the rest, i totally agree with the points even with the challenge partially, if it's a fair onee which is kinda rare in most games and that's why from software games are so popular this past decade, they are fairly challenging
