I agree, I think a lot of people fall into multiple categories. Generally you can get an idea of what the group as a whole leans towards, even though every single person might fall into different areas. But there is going to be some area that all the people run the best. The group of friends is really going to be what determines which games you play, as a whole, not just a single player. And some games, thankfully, give you multiple options, so you can play it with different types of players so it works even if you have a mixed group. Dead of Winter and those hidden traitor games are a great example of that.
