FontForge
An open-source font editor supporting outlines, kerning, OpenType features, bitmap fonts, and many font formats.
Why use it
FontForge lets teams add missing glyphs, build pixel fonts, tune CJK fallback, and generate subsetted files for engines.
Where it fits
Use art, animation, audio, levels, and narrative to make the game easy to read and its world convincing.
What to check
Font design and hinting require expertise; verify modification, embedding, and redistribution rights before editing an existing font.
