I did start a tribe of another faction, but it's been paused since they made fire.

One tribe is enough for me to worry about right now, my builders have completely different ideas to mine

Lol i have one tribe currently going in each game :P it's interesting to compare what has been improved upon in each game. Plus, when i get fed up w/ one tribe, i can always go play w/ another one :P

I have two tribes but one has been paused for the past few days. I've been too wrapped up in the first tribe plus the second requires babysitting for the time being. I am wiped out from playing my one tribe. Don't know if I will resume the 2nd one.

I can't either. One tribe at a time is enoght for me!

I usually start all 5 and do things a little differently in each. Typically at least one won't make it.

Once they get going (everyone trained in something and set to a task), they can be left alone for an hour or two with no harm. Until I have a big population and unlimited food supply, I pause if I'm going to be away from my computer for longer than that.

In VV3 I only started 4 tribes so that there will be two for each faction, and I'm saving one to do on "hard" setting later, using the faction I decide I like best.

On VV1 and VV2 I had all 5 games going at the same time. It gave me something to do during down time, like trying to get tech points. I haven't started a 2nd game on VV3 yet but I plan to. Since I didn't have a guide when I started I was worried about how well I could play it. I completed puzzle 16 yesterday. So off to some more tribes!!
