More lore? This post is about alphabets.
I'm not going so far in Geoshie as to actually make a language, or even the semblance of a language - for obvious reasons. In any case, I'm not sure how much Geoshie would benefit from a system like that even if I could pull one off. What I do love, however, are games like Aquaria that use their own alphabets. Aquaria is actually a great example here because it doesn't teach you the alphabet - it gives you enough of a translation to figure out what symbols correspond to what letters and leaves the rest to you to do on your own time.
