honestly, its just free advertising. the reason people are allowed to post gameplay videos without the risk of violating copyright is because they arent uploading the full experience. you cant get everything out of a game if you are just watching it.
never have i seen videos of a game a really wanted to play, only to go, "well, i guess i dont have any reason to play it now".
the only time gameplay videos turn me off of purchasing a game is if they dont look fun to play. ive watched full walkthroughs of story driven games, but if those videos didnt exist, i sure as hell wouldnt have bothered to buy the games, as the gameplay didnt entice me.
