Well, perhaps then _simple_ graphics, i.e. stuff created using the
line/box-draw characters in the MDA card.

I distinctly remember enjoying playing a very graphical version of
Othello on my dad's first-generation (PC-1) IBM machine with only an MDA
card.

I probably still have it somewhere.  There are a lot of .BAS programs
included with the first versions of PC-DOS.
