i live in San Diego, but a part that's a bit chopped off on the map. (Mira Mesa.) looks great so far, you're right about chula vista/national city, they're both lower income areas, as is the area immediately south of downtown. really ghetto things up down there. once you get into the north park/hillcrest/mission hills areas, they're lower middle and just lower class areas. don't build too many police there either, there's obviously not enough irl. downtown is def R$$$ and C$$$ mostly, and will be expanding as the PetCo park things are done. also keep in mind the trolley extension being built running to SDSU, i don't know where you'll find a map online of it, other than it runs along i-8. that part would be best represented by el-trains, but the rest is ground-level trolleys. i've heard it'll be done this year, so it'd probably be best to include it, since it's already in place in many areas. del cerro / sierra mesa are both pretty nice neighborhoods, upper middle and middle class, as is tierrasanta mostly. overall the $$ values you assigned looked pretty good too. good luck. dave
