Some months ago, when I last played Nexuiz, I encouraged various north american players to create clans. My reasoning for this is because I wanted to see people improve and I wanted to participate in clan vs clan matches with advanced strategy and gameplay.
I found that some people weren't interested in forming clans for various reasons. I think some of it was just the cool factor where they thought joining a clan was dorky or whatever. I really don't know the real reasons because they were vague. Some people showed a little bit of interest, but they didn't act on it. Some people didn't know how to form or join a clan, so I started this basic tutorial to help some of them. http://www.nullgaming.com/clans.html
Aside from not liking the word "clan" itself (I think they should be called teams or something else), the thought of having clan members training together to work on team communication, strategy, technique, etc...is the thing that really kept me interested in Nexuiz. That was the holy grail that I was searching for. That is why I joined TSA (www.stormassault.com). If there aren't other clans to match, then obviously that plan fizzles.
So, if there are more clans being created, then that is good news. It might prompt me to consider playing Nexuiz again soon. Though, I do need to build a gaming machine first. My laptop is getting a bit old.
