Emotional system by LotuxPunk Rejected
The TARDIS is not a machine, it's alive! Why not make the TARDIS like you or not? If he likes you, he'll be more precise in his settings, faster, more cooperative. But if he doesn't love you he'll make weird noises when you want to touch his controls or land in the wrong place voluntarily. If the TARDIS crashes or is hit, it will love you less, but if you take care of it, it will love you!
