So my younger brother is getting started in the RPG space ( <3 ) doing variations on a Lego RPG (they make those now?!). I'm advising him on his GMing.
But, crazy twist, he wants to have one of the player characters be an orc, the otherwise generic non-human (read: acceptable target) enemy. Which is neat and a variation I'm totally behind.
So, with some prodding, he came up with a "the orc was orphaned and raised by humans" idea as an explanation for what, the actual heck, an orc was doing fighting its own. Now, that's pretty neat, especially for a first go, but it begs all sorts of other questions. Do these species eat the same foods? How easily does an orc speak the human language? How does it deal with physical/medical issues that a species's support structure might otherwise cover? (I mean, we've got puberty, and that's pretty wacky. Imagine not having had people around to explain it!)
You get the point. It's a good idea, but could use further pursuit. Any ideas? Note that the setting is still in its infancy: I was hoping that answers to this question might help us zero in on how the setting should play out.
