Historical research into the history of table top gaming should be on topic.
Historical research into the history of table top gaming should be on topic.
The line "practical answerable questions based on actual problems that you face" is quite outmoded and while it was suitable for the trilogy sites, has been and should be largely abandoned by SE 2.0 sites (though it's still a part of the FAQ it's wording is up for revisions).
That said, it's a good criteria for most questions. The problem is when you have a general interest question that is otherwise quite good. "Did D&D invent the usage of XP for experience points?" is a good no topicon-topic question (provided the author does a bit of prior research and informs the audience of such).
