I was also a gamer before playing The Sims and still am. I'm very used to concepts getting mixed together, as many games feature some kind of nod or several towards something in the real world or something from a different fictional universe. It's all in good fun and a healthy reminder that games, after all, are just games and shouldn't be taken too seriously.
There is really nothing more to it than that, the way I see it. I don't believe for a second that the developers set out to intentionally disappoint people. If anything, they probably wanted folks to lighten up a bit in these dark times. It's really tragic that they instead have managed to fail so miserably. However, many do seem to be excited as well. They may not be as vocal or geared up to wage war, but at least a good chunk will still have fun with Star Wars in The Sims.
