My VV1 game is running alone since… the beginning (2 years, I think) and every thing goes well with the GC and 90 villagers (or near)

My VV2 game is in Pause because it can't be let alone: When the fire is over, villagers may be sick and they die!!!

And I'm playing my 2nd tribe of VV3, so I look at the 1st every day and I don't know what could happen if I'd not do it. Every day I make the chief lecturing to the kids, so they all have a little skill in something and are able to begin a task. But there is 1 or 2 who are "unsure what to do"! In fact I don't know what could happen if I'd let them alone, I don't dare of it!!
