A real man seeks to confirm his manliness by posting on the internet.
Now watch me headbutt this tree TO DEATH!
I think we're looking at this a little skewed, as what makes a man a true man is many different things to many different men.
I think as regards gaming, you can't get a better man than Ezio Auditore.
I think you can't get more ridiculous and frankly warped than Marcus Phoenix and every other muscle bound spaz mareen out there.
Yahtzee had an excellent Extra Punctuation about it.

Personally, I think that a man that finds it difficult to express his feelings is fine.
I'm actually quite the hot head myself, so I express myself fairly lively if it's about something important.
If you're in a relationship and you can't express yourself to your partner, it's probably going to cause problems.
It's never healthy to suppress your only feelings on something.
I think we're confusing machismo with the qualities that make a mature adult male.
