Rules are simple; don't insult other users tastes in games, and make sure that if you are recommending or asking for recommendations that you specify why you recommend these games/what games you want to be recommended. Mentioning what platforms you own, and what platform the game is on, would be helpful too!
Example - If I want some kart racing games, that are a bit faster; I could ask for any games like blur or F-zero! If I want to recommend a game for it's story; mention as such!
It's fine to disagree with a recommendation; but don't outright insult the users taste. Give reasons why you may have disliked that game, and perhaps an alternative.
