The only Real Worlds I really liked were the first NY season, San Francisco (my all-time favorite) and Miami. London I didn't watch much, Boston irritated me (even with my Soror Kameelah), so did Seattle.
I lived in a "Real World-"style situation in 1989 with nine other folx for a post-graduate program. Big house near the UC-Berkeley campus. We had our share of tension.
