No matter how bad a game can be, it can look awesome with a great trailer. Even better if the game is good too. Sometimes the trailer doesn't have anything to do with the game either, but who cares, it looks awesome!
How about posting here trailers of games that clearly stand out and make you go "OH GOD! I NEED THAT GAME! NOW!!!"
