Yeah, the normal sized ones have to move a little to keep it realistic, but some types of gamers will accuse developers of cheap fanservice when they bounce even the slightest bit.
I do feel kinda bad for the women they're attached to when they do bounce, though. Moving boobs are uncomfortable (thank god for sport bras!) and may even hurt when they are big enough.
I find it funny we've got breast jiggling down pat better than graphical clipping issues. I remember liking FF13 really put a lot of effort to avoid that with Lightning's cape-scarf thing and Serah's ponytail.
And yeah I'm a fan of the sports bra too (the days when I forget to change into for the gym are annoying). Since I'm sometimes too lazy to change after the gym or go see my boyfriend right after I'll be wearing it and he calls me uni-boob (I think I need a new style). :(
I'm not into facial hair on my heroes. Ick. Iiiick. No please. I don't think, in gaming, facial hair has really improved how a character design has looked for me.
On the subject of breast physics, I agree that a little bounce is best, and most realistic. I'm still fond of Lulu's from X most, I think, when it comes to a larger, exposed bust. It's there, as it should be for a woman that exposed, but it's not terrible and bouncy in her average scenes. You really only see it if she moves her arms and after the battle.
In truth, to be realistic they probably should have bounced more, but eh. It probably would have been too much, then.
Lulu's jig was great. Not enough to distract but enough to make you look harder. Despite the obvious goth look to her too (and how some people love it or hate it --- specifically her belt-skirt) I loved her design all in all and took the idea of a "black mage" to a literal but interesting level...
