Not an argument, or atleast not a real one, forgive me if it seemed so, I tend to have fake arguments with people for both of our amusement.
In their sixties? Wow, DF must not look too different from the original games that they where alive to see come out.
I assume you mean the original computer games. The first game I was alive to see come out was some kind of card game featuring lambs jumping on fields of grass and flowers.
The first computer games I played were in black-and-white (or black-and-green, or black-and-amber). They used only alphanumeric symbols with no graphical symbols at all. Later on there was color and several sets of non-alphanumeric symbols. A lot of them were actually text-only games because processor power and memory capacity was limited. Graphics was an output function from the CPU rather than from a dedicated graphics chipset. Even games on dedicated game machines were not much better graphically, and of course they were rather arcade-ish. DF is much, much better than any of those, although of course they possess in my mind an aura of the fresh and optimistic exploration of life that I was experiencing at the time that I played them. I mean, there is nothing intrinsically wonderful about shooting Klingons on a 16x16 field of blanks and asterisks, except for the fact that I was vying with the other laboratory personnel for my turn playing on the PDP-11 before the boss came in and we had to reboot it for work.
