On every question (correctly) tagged with game-recommendation, somebody comes along and leaves a comment reminding answer's how to address the question properly. To make this more permanent than the ephemeral comments, RPG.SE mods should request a permanent banner be set up.
For example, Physics.SE uses these on book-recommendation questions, see Shog's answer.
EDIT
So this edit is mostly just to bump the activity to the front page. It would appear that the answer by SevenSidedDie is a minor tweak on the wording in my answer and the difference in votes between the two could just be attributed to age (mine came first).
Therefore -- in order to resolve this question and move on, I'll give it another day or so for comments for/against and I will accept SevenSidedDie's answer. Any objections or further discussion, leave a comment or pick it up in chat and let's finish this off!
