Ideally, we'd be able to manually change the looks of our parents and siblings before launching into the game world, but even randomize buttons and the ability to see their height would work. Currently, the only way to alter their looks is to keep backing out and tweaking your own sliders slightly, which re-randomizes the parents and older brother (and presumably the younger two as well, but they aren't visible at that point). But it gets pretty tedious having to do this, sometimes quite a few times, to get all 3 looking halfway OK, and you still can't see their height. I've had a lot of "false starts" after loading into the training grounds with my brother looking me eyes-to-nipple because he's so tiny. Whenever that happens, it seems like all the other family members also show up as being extremely short in the encyclopedia, with my character being the odd giant out (and I don't even max out the height slider).
