I usually play like this. I tend to play almost realistic as possible and having a sim go from Windenburg to Oasis Springs in a matter of seconds just doesn't feel right to me. I let my sims travel to worlds that seem reasonably close. The newest world and Del Sol Valley to me feel like they would be close by so I travel between the two freely.
@mightysprite has a similar legacy challenge here on the forums. I'm playing it as well, each world has a color that the current heir wears and the worlds have certain traditions to follow weekly. Travel is limited to only nearly worlds and each world has certain careers available to them. It's a fun challenge
