Well I have heard several from my own parents, even being old enough to do what I want I normally hear things like:
"Videogames are making you antisocial" (yeah right, I have a girlfriend and several non - internet friends)
"Videogames are making you dumb" (I am a freaking professor, dammit, I teach technology)
"You are wasting your time" (It is my time, and in fact videogames have teach me several things, for example by presenting me problems to solve)
"Stop playing all the time" (at best on a week I play 5-7 hours)
"Don't you feel bad for killing those guys on the screen" -side note: this was said to me while playing ratchet on my own house by my father - (They are just pixels, I am not the one seeing each WWII movie ever made or boxing matchs one after the other)
the list can go on.
