probably old geezer, anyone that i personally know over the age of 35ish has...absolutely abysmal hand skills when it comes to video games of any kind. not to mention they always pull the "heh, gettin beat by an old timer when i haven't played since that summer of 72'? pathetic"
(that happens with sports and shit, it gets really annoying to me when they constantly grieve about it, so i would think the same applies to video games if an older geezer actually beat me at one.)
young kids generally are either laughable or have been playing twitch games since they could pick up a controller, so there are plenty of them that are better than me at some games. (know a couple kids who did MLG COD/halo 3, they smoked me decent enough, although they weren't asshats about it so i didn't mind in the slightest.)
