Kind of like WoW only more freeform and with a Fag Factor of 11 instead of just 8.5.
I messed around with SL a bit a few years ago, I did some scripting, and created a few interesting objects... Boats, amusement rides.. blizzard in a can, and a Wonkavator amongst other things, but then it became all virtual casinos, and furries.. and furries running virtual casinos..
oh, and virtual furry dance halls, and furry prostitution. In my virtual abode, I kept a furry head on a plaque - but it just got to be 'too much' to invest in.. It was like hanging out in a big, furry DU..
