This is a recreation of the proportional dialog font used in the 1991 MS-DOS platformer Commander Keen in Goodbye, Galaxy by id Software, sometimes known as Keen 4: Secret of the Oracle and Keen 5: The Armageddon Machine. Its glyphs are 8 pixels tall with a 2 pixel stroke width and x-height of 5 pixels, making it nice and easy to read. Similar fonts appear in other pre-Doom id Software titles.

Note that, due to the non-square pixels of DOS's 320x200 video mode, you may want to stretch this vertically by 20% to to get the most "authentic" appearance.
