i usually don't throw suggestions around, but more upgrades for things, even for the tube and care facility would be neat, a all-you-can-eat buffet situation mebbie, but also some more personality archetypes, like someone who's -really- into it, and someone who's really determined to stay mobile and independent in spite of their large size, a "should be immobile" if you will..
and a fashion disaster that avoids a mumu and opts for something else instead, even if a little too small, etc.
that said i'm interested to see what follows up next update wise, keep it up.
