Can I play without facebook?
If it's using one of the facebook apps... then no
Because the laptop I had with a webcam is dead.
This skype chat isn't gonna require video, is it?
I don't think it's possible to do video chat with more than 2 people. I've tried before and either I really suck at Skype or the ability to do it is not available.
Group video calls are possible I believe.
So, you're more than welcome to show up, but you'll be 'that guy' who wears the reflective glasses and never says anything swearing he'll make it to the pros one day.
