I think the community at P.SE is an excellent crowd when one wants to find out good resources for puzzles (/riddles/...). However, as the site policy is rather strict on opinion based questions (which therefore don't have a valid answer), I'm wondering if the following question category would be suitable for the main site or not:
Asking for a recommendations for good puzzle books / sites / games...
I personally think they are within the scope of the site, but then again, I'm not sure. So instead of asking them on the main-site, I wanted to poll the general attitude towards such questions here first.
My impression is, that questions like
"Can you recommend good puzzling books?"
is clearly too broad and invites a VTC immediately (and rightfully so), but if it becomes more specific? For example:
"I'm interested in logical puzzles and would like to find a book which both offers some non-standard puzzles, but also teaches ways to solve them. Can you recommend some resources from your personal experience?"
"Can you suggest good sources for geometry-based puzzles? If possible, can you give details on how 'mathematical' those sources are?"
I think such questions would be in the scope of the site, but it might be opening a Pandora's box, so what is the general opinion about such questions here?
