Me and DS6 play. He just likes to ride around on the monorail and walk up to random people and say "Hi", wave and walk away. Pretty funny to watch, actually.
All 3 sons are on now, and me, of course. Makes if VERY difficult to get on the 2 computers with 4 of us fighting for time on them.
2 of my sisters are also on (don't live in the same house though, not even the same state). They are on all the time so I usually hang out with one of them.
