No, I approve of my players finding ways to flesh out the world. That's part of the world-building and back and forth cooperation I mentioned in my "What to Expect" message, and I love seeing it in my players. Continue apace.
The Law of Awesome-The success of an idea, plan or scheme is directly proportional to how ludicrous, ridiculous, or batsh** insane it sounds upon explanation. "I've got a plan that's so crazy it HAS to work!"
In one of the AIM campaigns I play in, my boyfriend plays the only male character of the party. We joke about it OoC and call it his harem, though in reality he only has eyes for my character (due to backstory integration we have). The awkward part? She's pretending to be a male and he doesn't know her true gender. Hilarity ensues.
