I came up with this idea in the context of How do we get questions per day count up? My answer is buried there so here it is again, as it is a possible answer to the above question:
Game recommendation questions were (are) so popular that I think it's worth brainstorming what kinds of templates could be used to solve some of the issues they bring up. I think there's an objective type of question here that is being completely ignored: an answer which is an objective (or nearly objective) list.
Example of non-game question: What towns are within 4 miles of London, England?
The answer to this is objective, right?
Example of very objective game question: What games were made by EON before it went out of business? Please provide one game per answer with either a brief description of the game (this particular Q is low value because you can easily find the information elsewhere).
Now for one that has a little subjectivity creep in (and for which I actually want to know the answer!):
Which games are obviously Gateway Games, where gateway games are defined as . . . Please list one game per answer so the answer can be voted up (if it's a Gateway Game) or not voted if it's not a Gateway game.
I know that stack exchange mechanisms are not particularly well suited to this type of question, but if you can nail down a precise definition for "Gateway Games" (which was attempted here), then the answer to this is actually an objective list, just like the answer to towns within 4 miles of London. Not only that, the objective list would be roughly ordered by popularity and degree of adherence to the definition, which adds additional value.
I would love to see questions like this. Other examples:
Which wargames offer simulations on a squad level that are on par with Squad Leader?
Which games have had the largest influence on Game Design over the past 40 years? Please list one game per answer and describe the influences this game has had on the industry?
What games can be enjoyed at various levels of complexity, such that both a 6 year old and a game-loving adult parent might enjoy playing together? Candyland does not meet this criteria as it is boring for game-loving adults. Bridge neither because it is far too difficult to learn. Rat-A-Tat-Cat, Backgammon, and Checkers are good candidates for this list because they can be enjoyed immediately at a very simple level but actually have significant strategy components that can be mastered over time and are therefore of interest to game-loving adults. Please list one game per answer and provide some reasons for both the adult and the child to enjoy the game. If there is a way to handicap the game, please include that information (i.e. Checkers - adult can start with 1 or 2 pieces removed).
TLDR; Can we do a restricted form of Game Recommendations where the questions have answers that are lists that are objective or close to objective, because they adhere to well defined criteria?
