would be funny to see the dog goin to the toilet. specially if it lays a fresh biscuit in the middle a path for someone to step in... heh.
but yeah man, you is right. it is certainly the little things. i wrote a huge post about it for GTA a while back.
some little things i'd like are
more haircuts
a beard that grows over time, and maybe a razor to keep it in check.
variety in clothes
lots more emotes (NPC interaction is a great idea BTW)
i like the idea of other NPC heros living out their lives too, buying a house, getting married etc.. maybe they would compete with you for sidequests by completing ones you fail to under go for fame, and could lead to being a enemy thats a real pain. or by working and drinking together become powerful allies..
weaker weapons could break or could maybe be upgraded
forge new weapons from listed materials..
being able to turn out lamps outside to help avoid guards
catching cold
smoking
other dogs
being able to eat chickens and other animals for health! :devil:+5!!
just a few... dunno if thats 'little' enough tho!! heh.
