My sister bought virtual villiagers for our mom and we're the ones hooked. I have solved all the puzzles, but now what. Is there a purpose for the cave? Is there anything else to do now or do you just refresh and start over. If that the case I bummed, it was fun the first, but don't really want to just keeping replaying it.

There really isn't much to do once you've completed the puzzles, but you could try the game on a different difficulty level. I'm just trying a hard level tribe in VV2.

Although there may not be much left to do with that particular tribe, there is still a lot you can do with the game. There has been a lot of good discussion about this topic in the forums, and you can check out some of the best comments and ideas in these posts:

I should have known that LadyCFII would come up with some awesome links for you! LOL

Have you considered Virtual Villagers 2 (that is where the cave in VV1 leads to), Plant Tycoon, and/or Fish Tycoon?
