What I'd like to see in VV3:
1. More collectibles appearing more often.
2. More "gathering" food sources, such as scattered bushes that the kids can pick from. Perhaps one can appear, be "pickable" for say 100 units total and then disappear. Gives the kids more purpose in helping support the tribe.
3. Nursing mothers should be able to have a few other limited functions instead of just sitting around with the baby. Perhaps the "gathering" from small temporary bushes(mentioned in 2 above), mushroom picking, etc. I mean, even in the most rudimentary lifestyles, nursing mothers can do _something_ besides haul the baby around.
4. Bird nests from which eggs can be collected.
5. More puzzles
