I guess I should provide a conclusion to my "Into the Future" story arc, although it is not a happy ending. Take a look where everyone is looking. What's that up in the sky? Is it a bird? Is it a plane? Is it the end of the world?
Well, for one it was. I managed to get everyone down in the cellar except for A-1, who had turned invisible when he became an elder. (Plumbots should not become elders, but he was glitched, and since there was no elder body for plumbots, he turned invisible, except for the eyes.) In the confusion, I did not see him, and he was left outside while the rest huddled in the cellar below the basement.
And that's the last Sims picture on this computer. Eventually I started playing Sims 3 again, on a different computer, but that is another story.
