I was from the TS2 world as well and I can assure you that the new world isn't as limited as you might think. By limited, I assume that you mean there being less stuff to do? Well, that's true, but it doesn't really phase me as the TS3 world is very different from the TS2 world.
And remember a lot of the stuff Sims in the TS2 world love such as vacationing, dancing at nightclubs, and owning businesses all came with deals that came later. I recently heard that TS3 Sims will be able to vacation again in November.
