Don’t be a twa*.
Assuming that people don’t have any other interests because they had a passion for truly hardcore and oldschool shooters like Quake or RTCW as opposed to mainstream games like Halo or CoD is pretty stupid. “Girlfriend girlfriend girlfriend.” I’ve had girlfriends, one of which liked ETQW. Does that make her a sorry ass loner, too?
Some people enjoy shooters as opposed to things like sports, and play them socially, or competitively because it challenges them in ways they deeply enjoy. So don’t be surprised you can’t understand it if you like to play them casually. That’s fine. But move along, this argument is not for you.
On the other hand:
That’s pretty true. Shooters do suck pretty hard these days because they’re dumbed down. For a simple example: Jumping through a window in CoD = running up to a ledge + pressing a button, compared to Quake or ET, where you’d circle jump + crouch while aiming at the window. Far less engaging, and it starts stripping the game of layers of elegant nuance that enhance the entertainment. On the other hand, there are other great things in life.
If you’re not playing games, you have so much more time to enjoy other aspects of your life. : P
So use it!
