I am the same as Warren.
I was in the army. I am a psychotherapist. I am a Buddhist. I love video games! I have been playing them since I was a kid and got to play Missile Command on my buddy's Atari 2600. And I am a gentle man who abhors violence.
Now, of course, I play a lot of different games and have over the years. If you name a gaming console or game, I have played it from Mario & Kirby to the entire Xeno Saga series to Halo & Borderlands. Admittedly, I do enjoy FPS's. I am playing Crysis 2 again through on Super Soldier difficulty, and it is relaxing for me.
But with all of this said, I have known and know plenty of women who also enjoy FPS'. My S.O. is one of them. Sure, she adores Hello Kitty games on her phone, raising Petz, and dealing with her inventory in Skyrim. And she also loves playing FPS's with me. We are avid Borderland's fans. She & I played FEAR 3 a lot, and you should have heard her giggle when she possessed a soldier, turned on the others near her, and blew the shit out of them.
I am impressed that she can hold her own in Crysis 2 on Normal level!
Freud once said that a cigar is just a cigar. What he meant was that often times there really isn't a lot of deeper meaning to a behavior. Humans have been fighting wars since we evolved from apes. We will be fighting them forever I am certain. We also enjoy games, revel to a certain extent in others misery, and are for the most part just decent folks who really do know the difference between fantasy violence like in a movie or game and the real, tragic shit that occurs around us.
Some don't like games. Some don't like FPS's. Many others do. Most are male, but not all. And that is just that.
