I don't pay much attention to them because I'm too caught up in my own households, and they're just background. However I do wish that there was some sort of progression with them, instead of all of them just growing old & dying out. I'd rather see some Landgraab & Goth descendants than the random townies the game keeps generating to keep the NPC population up. On the other hand, that may have been one of the things that contributed to the lag problems that plagued TS3, and unless you used a mod, or read the daily newspaper you couldn't really keep up with it all anyway. So I would take a smooth running game over the lives of sims I don't really care much about anyway.
