Some notes: Single mentioned priorities are not included, if they didn't fit in any of the categories above. Also different detailed priorities are in the same category as long as they share the same overall topic. Posts with more than three priorities got all of them taken into account, but if somebody wrote more than one priority that matches the same category within his post, it only got counted once. If one priority includes several categories, they got split. E.g. a trade, economy and pop priority is seperated in one count for trade and one for economy and population. Categories with two or more aspects are merged, because they are most of the time mentioned together. Specific faction DLCs are not included, because there are just about 2 to 3 different posts including them different factions currently.
