I don't see what is so hard to understand about the rules. In that thread it was mentioned that "you can talk about the game a few days before it's offical release, because that's about the time you may get the game thru the mail/some shops selling early"
So in other words, saying YAYYYYY! I am enjoying Gears of War next wednesday or thursday is fine, just not "ohhh look at Me!!! I am playing Gears of war 2 weeks before it's release!"
It was also mentioned that if you can provide PROOF that you have the game thru legal means (IE, you email a Mod and show proof that you own a game shop, or a picture of you holding the game in your hand or something like that) then it's ok to. But that is down to moderators choice. I really don't see why people are complaing about this so much....
