More clues for 7, 8, and 9 since people seem to be stuck on those.
7 - The newest entry in the franchise has quite the controversy surrounding it. The previous game to that was also not well-received, furthering my disdain for societies.
8 - A generic shooter? Way to be irrational! It's clearly an RPG.
9 - A game that's often been copied or remade (only 1 was official) since its release, with a number of cancelled projects as well. In fact another unofficial indie remake/spiritual successor is in the works, release date: unknown.
That's it for clues.
