Do you know fonts that feature character alternates prominently? I cannot think of type that I've seen used which used variations on characters to lead to the appearance of natural looking hand written text.
You'll sometimes find them in other fonts, though; Hoefler Text's italics have a whole bunch of "swash" alternates, for instance, which can be a lot of fun for titles. (Both Zapfino and Hoefler Text are standard fonts on macOS.)
Note how in the 'Dungeons & Dragons' example none of the repeated characters look alike. It only uses ligatures though, not contextual alternates, so words like 'egg' will still look mechanical.
