To make our game look better and uniform across devices, we want to use a nice embedded font. It's easy to do with Corona, just add the font file to the directory and specify it's name in a config.
The problem we just ran into is acquiring the fonts. I didn't know much about typography until now. Well it turns out there are thousands of font designers the world over making beautiful fonts and charging ludicrous prices. The first search yielded font shops selling fonts for $1,000-$10,000 per app. Who would ever buy these?!? The value that a great font adds to the game is, say, 5%. So to justify these font prices, the game must make $20K - $200K. There are very few games earning that much.
So a heated conversation about the craziness of this world later, we returned to google to find several collections of free fonts. God bless the open source.
Great looking fonts too!
Also useful discovery are these lists of fonts that come with iOS:
