I guess the idea of game suggestions, is if you think of somthing 'yourself' that can fit within game guidlines and storylines, it can be considered for use. If you have a suggestion, that is common among a lot of games, but again, would fit under game guidlines, and story guidlines, it can be considered, but if you ask for somthing that is unique, to a specific, game, it will be shot down, unless they can edit the idea, to be relative to 'this' game, and be different enough to 'not' be plagurism.
this game cannot afford to be sued, becuase it is a non-profit game.
that is why you have to take suggestions seriously.
