say you have data sources with pagination, where you iterate with page and per_page
http://host/articles?topic=action  (page = [0,1,2,...] per_page = 10 | 20 | 30)
http://host/articles?topic=puzzle  (page = [0,1,2,...] per_page = 10 | 20 | 30)
http://host/articles?topic=shooter (page = [0,1,2,...] per_page = 10 | 20 | 30)
http://host/articles?topic=rpg     (page = [0,1,2,...] per_page = 10 | 20 | 30)

Each article is tagged one and one only for the 'topic'. And then, you
realize that some topics (action, puzzle, shooter, rpg) are actually 'games'
so you define game is a set topics [action, puzzle, shooter, and rpg)
