To clarify why the question was closed, it is most likely because the question is yet another repository, not entirely because of the estimated answer yield. If you'll note my comment on that question, I explain why that metric is also stupid for both closing and reopening anyway. The scope of the question, which is genre X on platform Y, is what should be judged on, not the fact that platform Y is not likely to have a large number.
So should the question remain closed? There's no solid judgment. There's a lot of back-and-forth going on about whether game recommendations and listings are appropriate. Please check out the earlier 3 links for reasons on closing given by some of the community. Also check out here, where I explain why I personally think we are horrendously poor at supporting repositories, and this selection of discussions with voices on both sides of the debate.
