It depends on the game genre. I haven't come across much stereotyping in adventure games as compared to say, action or fighting games.
This is true as well. RPG's are also another example. I know some RPG's throw in a woman with chainmail bikinis but most western RPG's don't. In Baldur's Gate, a female warrior/paladin/ranger character would be bigger than all males who weren't warriors, rangers or paladins. Meanwhile she would be equal in height to male characters who were warriors/paladins/rangers.
