In VV1, if you have all the tech level, they want not to work at research anymore! But you don't need tech points anymore!
In VV2, it's not more easy to maintain the tribe because you need to gather the fire or your villagers shall be sick!

Didnt give up , even though the tribe was all boys

Still going strong from when I first started! I have VV1 and VV2 and never had any major problems. I'm thinking of starting a new tribe on VV1 to renew my interest in that game, since I usually just check on them and stuff. I've been a pretty good goddess if I do say so myself.
