I asked the question at Can I legally make a free clone of a game and use the same name? because I read a question that basically asked the exact same question in the same forum ( Is it legally possible to make a clone of the game?) but didn't answer the question of whether the same rules applied for a free game. It really surprised me that people made such an issue of the appropriateness of the question to the point of closing the question. Why is one question OK and the other off topic?
Even consulting the FAQ, I find the question to be on-topic in the area of project management. The name of a game is an important aspect of publishing, which is an explicit component of project management.
