There is usually a pretty decent turnout from the CSGO crowd and we normally even bring friends/family (Fatty brings his kids, Mav and his entire offspring of CS players come, and Shaft might even expose his son to the madness this year!)
I quite honestly don't understand why there isn't more excitement for FFO from the L4D crowd. If we had an equal amount of participation from there (and it's a much larger group), we would be able to have a pretty big event.
I think that everyone who's been to FFO can say that they had a great time
