I agree with Rockmower. The three VVs so far all build on the solid foundation laid by VV1 and improve on it. To just repeat VV1 in a slightly different setting wouldn't be any improvement. That said, for sheer playability, I think I prefer VV2 at the moment. The game balance is about right; it's important not to over-extend the tribe, but also not to be too cautious. To make techs more easily attainable by reducing the points required or by a stew would spoil it. The game is meant to be played over a period of several days, not hours.
