Most of my gripes have been pointed out, even this one, but the hell with it.
Characters drinking. Freelancer, pretty much any Bethesda RPG, the Mass Effect games, Dragon Age 2, and many many more, all get this horribly, jarringly wrong. Red Dead Redemption did this quite well, if I recall. All you have to do is position the camera properly. And, if you're feeling brave, perhaps model in the liquid being drained from the glass. Just for the love of Jebus stop showing us people raising empty glasses to a few centimetres away from their face, swallowing, and then going 'Ahhh' as if the sip of sod all they just imbibed was God's own jizz.
Also, thinking about it, that little head shake that all the Bioware and Rockstar protagonists do after drinking. Shepherd is a badass, one sip of space whiskey isn't going to make him shudder like a 14 year old sneaking vodka from his Dad's drink stash.
