How about doing something like Ultima Online (UO). They are both owned by Mystic, so I think it is a valid comparison. In UO you get to choose a reward from a list. Clicky here to see it. Take some time and make some new gift choices for years 1 - 3. Then make choices for 4 and 5. Give everyone 3 choices for free at amnesty or after 1 year. Then give one more choice per year of account age. This way, if someone has their dog statue but wants something else for year 1 they can choose it. I have saved up 3 choices in UO because I cant decide what I want. Only people that meet the age requirements can use the object. A 1 year old cant use a 2 year old item. A tree would mean they cant put it on their lot if they are just 1, but they could eat fruit from someone elses loins, I mean tree. I would be will to wait a few months for amnesty if the devs would make gift choices like UO has done. They could even use objects created by CC makers that look good. All they have to do is add a script. For the first year it could be an object like the pet statue, when you "worship" it, one of your motives would increase depending upon the object type. This could really make the game fun.
