not sure if I understood the suggestion procedure. But here goes:
Suggestion Idea:
This expands the idea of "sorting the "join game"-list suggestion".
when wishing to join a game the player may "select" between the games with his preferences.
Specifics:
The Interface could be similar to the "create game" interface such that the player put checkmarks in the preferences games of his choice.
Similarly, the output could be similar to the current list-view.
As I assume these are stored in a database the underlying functionlity will be close to :
SELECT games
FROM TheGroovyGameTable
WHERE
GameType IN ('standard', 'Terminator')
AND
PlayOrder IN ('Freestyle')
AND
BonusCards IN ('Escalating', 'No Cards')
If not too much of a bother these could then sorted according to how many has joined.
Why it is needed:
It is necessary to facilitate a decent game finding experience.
Priority** (1-5):
5, the number of join games are so large that it is troublesome to sort through all the pages.
The technology should also be fairly trivial to implement as most of the interface is already present.
before they lock it anyways
