I wouldn't put too much weight on curvature differences, that's an inevitable part of turning curved letterforms into a bitmap font. The letters would obviously have required significant pixel-by-pixel tweaking to look good on a 320x240 raster.

Quake didn't even present the bitmaps in a consistent aspect ratio or size, it did a 1-to-1 pixel copy regardless of the target pixel shape/size. Quake shipped with a 320x200 default resolution in 1996, with configurable support for a variety of resolutions including 320x240. Over time, most people ended up on a 4:3 resolution on a 4:3 display.
