Well, I've been playing around with the Serenity RPG. I could see about designing a well-balanced (game-wise, not necessarily mentally or physically). Regardless, bringing in a new character. I could always bring in a character I made for that system instead of a doctor: Toast. A scientist, assassin, and most importantly, a chef. Could use that. Especially since in that system, she rolls d12+d8 just for the skill, before the attribute (d12 is the normal maximum for starting characters, but Toast has some assets to help with that)...which makes baking a delicious chocolate cake from just protein packs is not only possible, but actually quite easy.
Might be nice to have an accomplished chef. Maybe a Companion. I haven't made one of them yet...
Nor do I have to. We'll see when the panic settles and the miscellaneous people on the ship can introduce themselves without freaking everyone out.
