What is there to do on the ubrz sims in the city?

lots more then the originals... sims urbz allows you to unlock different items and areas without having them there already. you get to join a gang or a 'group' and you actually get to play the sims while their working. (you control how they work and what they do) E.g jewelry making, the more you work in this section the more skilled you will become in Jewlery making. all round its a lot different... i personally like it
