I only know of one tribe that I have seen that they have at lest ten members of there Tribe in [strike]Beta[/strike] now. That could start there tribe if they was to put in tribes today. Hopi could do it after a week or so I think, We have the members but a lot of them are staying away for now, So that they will not burn out before the game goes live. I also know that there was one or two groups that seemed to play together when all we had was two spawn point's. So there is a good bit of people that play the game per week.
What I was wanting to see, How many active Xsyon gamers would want to (at lest at the start) go in together and make one big tribe as we learned how the tribe works. Later after the newness of it wears off and more tribes have there members in-game we could break apart and start making our own tribes. But there will be things that only large tribes can do. Like Flags and Emblems for sure, There may be more that I don't know of.
So ...... What ya think? :S
