I notice this thread was closed due to be subjective and argumentative https://gaming.stackexchange.com/questions/1835/what-are-some-good-turn-based-tactics-titles-for-the-pc-closed. I found in particular that thread was extremely useful. I agree with the fact that thread was closed since the OP used the word "good" in its question. However, the field of turn-based-tactics game are very small compare with the rest of the games out there.
Recently I asked a question https://gaming.stackexchange.com/questions/2866/what-are-some-srpg-trpg. I noticed the various moderators having discussion on whether this is an appropriate question. My question then is, why is it not an appropriate question? What is the policy here? I don't believe there's even more than 10 or 15 answers possible to that question.
To me, questions such as above is the same genre of questions as looking for a particular library that fulfill a certain types of function calls in Stack Overflow. I feel as if the field for these games are tiny enough that questions asking for knowing what they are should be allowed. However, to know whether that question has too broad of an answer would require the moderators to have adequate knowledge of the possible answer to that question. That is a thorny problem indeed.
Thank you for for reading!
