You'll find that men (and women) engage in sexual harassment and blunt sexual propositions in all industries.
I'll happily acknowledge that the games industry skews male and has its fair share of socially awkward people, but this example is not typical enough nor limited to the games industry for you to be making such broad generalizations.
The game industry seems to have more of the awkward types, and less women and other minorities in general. The only situation I can see being worst is an occupation where a group of guys are stuck together for months at a time without having contact with people period so you end up with a "what happens on the trip stays there," situation with guys hooking up with each other to combat loneliness.
