Doesn't sound weird to me. Many of us get attached to our little pixel people!

Some of us try to build specific tribes when it's all over. For instance, maybe a tribe with all the same hair-color (takes careful breeding), or a super race of esteemed elders, or maybe try to get every single villager to master a particular skill (mine is healing). These are easier to do once you have the puzzles solved... and challenging enough once you have the maximum population.

Hope that helps! Have fun with it!!
