Now, I admire The Sims as a game, but from a story viewpoint, there are two glaring problems. First, your relationship with those characters is like they're bugs in a jar. There's no empathy. And secondly, you've got this clunky, chemistry-set interface between you and them, with bars to show how tired or angry they are. It's all tell not show.
The funny thing is, I sometimes get the impression that some people outside of the field think that there's some element of security that we have in working on a theory that hasn't made any predictions that can be proven false. In a sense, we're working on something unfalsifiable.
The full name of string theory is really superstring theory. The 'super' stands for this feature called supersymmetry, which, without getting into any details, predicts that for every known particle in the world, there should be a partner particle, the so-called supersymmetric partner.
