More and more, I find that money, fame, and power reveal people for who they are, not necessarily when they are in abundance.
It's more revealing when these things are scarce.
Not all wealthy people are heartless.
Not all poor people are saints.
Your Personality Based on Your Gaming Behaviours
How you play a game predicts how you handle real life.
Resources, exploration, formulating a plan, meeting objectives, identifying goals / milestones, keeping score, etc.
They have their parallels in real life and it's difficult to override your tendencies to do things a certain way.
For example, if you tend to think before you leap, you are less likely to do YOLO things in-game.
If you are an explorer type, you are more likely to go off the beaten path and look for side quests and interesting locations in a game.
If you like to keep updated and current when it comes to consumer goods and electronics, you are more likely to spend your in-game currency as soon as you get enough to acquire that shiny new weapon / armor.
This isn't to say that watching you play a game will allow me to have a complete picture of who you are.
Because context, companions, and frame of mind have to be taken into consideration as well.
But it can give a rough idea of your likes, dislikes, and tendencies. And that's always useful if we have to face off or interact in the virtual world.
