Last night was the first time I encountered anything 'bad' and it wasn't bad in a minor way- playing the team flag game, I was on a team that was repeatedly destroyed by what was obviously a group of friends playing together. Which is fair enough! but kind of bleeds the fun from it when you literally have to respawn every 10 seconds!
In other news... I was playing a big team deathmatch, and settled down on a Karachi rooftop to shoot people in the head as they walked passed, and looked to the guy beside me- and noticed the name above his head- which I recognised. And sure enough, it was my local Comic Book Guy! What's the chances??
