in this package, the 8pt font for japanese was the bottle neck which hadnt been resolved for loooooong time. and the font in this package is rather neat and well thought one.
i think most of native japanese including me should feel enough presentation of the fonts if not "beautiful".
usually if the screen was low-res (320x200 to 320x256, i mean), japanese wont expect legible fonts especially for kanji. cuz at least 16pt or more size font is must.
that's the main reason why western computer system couldnt become popular in japan even AMIGA (most innovative time for gaming genre.) and later Dos/V (delivered total "shocks" like Doom, Wing Commander, Dune2/Command&Conquer... ) era. they were still using low-res screen.
we knew already at least 640x200 resolution is the least to display full japanese texts. you can realize how many japanese console games couldnt use enough kanji on low-res screen. (from nes/SG-1000/PC-Engine to PlayStation/Saturn.)
while main stream of our domestic computers having had 8 color 640x200 screen and onboard kanji-rom from the beginning (NEC PC-8801, Fujitsuu FM-7, and Sharp X-1. all top three was 8bit computer.), it gave a great satisfaction to owners as compensation for high price. and the period precisely corresponds to Apple][, C64, Atari, ZX80, CPC to AMIGA era.
soon later, NEC PC-9801 series of 16/32bit machines became standard for the purpose of gaming/buisiness which was natively 16 to 256 color 640x400 screen and higher rank onboard kanji-rom supported. although arcade machine and consoles still stayed in low-res world. and this period corresponds to Dos/V era.
so, i cant say "more" to the auther of this font. its already breakthrough.
if wider screen resolution could have been added as overlay for text output someday, it will become more eye-friendly for foreigner who learns or having interest in reading japanese text.
about the part of mods, each mods has own translation in ruleset file, so translator need to add the texts to each ruleset apart from general xxx.yml.
