I obsessively played my first nature faction tribe and thus completed all the puzzles, the collectibles and most of the awards far too soon to have really enjoyed the game. My second village (magic) is still not finished yet because I only play it when I want to have fun and really interact with their "lives". As to the collectibles...I know they will all eventually show up and I will exuberantly scoop up the nearest child and proudly watch them trot it up to the lab.
