My current project uses text glyphs as graphics for the game world, an approach that works very well for small numbers of glyphs and for text-based consoles. I'm using neither, though. I need a lot of glyphs, eventually 2,000 or more, and am developing in Unity3D. Unity's text-drawing capabilities could probably be coerced into something like a textual console, but generating the needed glyphs is simple with Photoshop.
