I do not expect realism in games like this, even the ones that are supposed to be set in what is our current world/times, but there is believable, semi believable and outright dumb, that sort of size is outright dumb, the weight of their size would more than likely crush the lower babies in their body due to the weight of the others above and around them. The only reason I have not just laughed myself stupid and ignored the game is that it does not seem to affect the player and their team mates, well not to the point I have played anyway.
