Find a specific field your language would be useful to.<p>I tend to think that having it be a scripting language (eg. one that&#x27;s ment to be used as, for example, creating quests &#x2F; scripting events. Like old Gothic [I and II] used to have) justifies creating it (and potentially could be useful, since the main contenders as far as I am aware are AngelScript, LUA and Squirrel - so there&#x27;s not a plethora of choices to choose from).<p>Though you could find any other field where the language could be used for.<p>Perhaps processing data, or maybe analyzing human language. Whatever you can come up with.<p>Then it kind of makes sense :D
