Would it be considered as redistributing the font if it's included in the game folder? What about using these fonts in a digital (PDF) game manual?
For the first question: YES. For the second, Depends on the format. If the font is embedded in the file, then yes, it counts as distribution.
Basically, Font copyrights seem convoluted, because the laws on the books were mainly written with printed material in mind.
Any regulations dealing with digital uses are basically tacked-on afterthoughts.
FYI, a "commercial license," isn't even enough for use in a game/software. You need what's usually called an "
"Application License" or "Embedding License" but the problem is, RPG maker doesn't encrypt it's font folder, so even WITH the proper license, you can't use it with RPG maker without it counting as redistribution.
The two ways around those issues are:
1. Use a font that is 100% free and can be freely redistributed. For example: The default RPG maker VX ACE font is actually one of those. It's not Enterbrain's font.
2 use a sprite/image based font: This is kind of a weird technicality, but if you convert the letters in your font to picture images, like a .png for example, then most of the rules for PRINT apply rather than for digital. So then a standard commercial license will be enough without needing an implication license. So, if you use a font to make game-over screens and such you're in the clear if you have a commercial use license. But you can use a script to replace the in-game font with a sprite instead of an actual font, so you can use that as a workaround. And then some HUD scripts (like Moghunter's) use sprite fonts. I know that sounds like a stupid rule, but it mainly has to do with the fact that fonts are basically vector-based and have infinite resolution so you can edit and re-size the symbols on the fly, while once it's in a sprite or an image, it's frozen into it's current size and pixel resolution. For example, with web pages, you need an embedding license to use a font on a web site, BUT if the font is only used for thing like banners then you only need a commercial license.
