Bad endings?
I don't think it's possible to do anything *wrong* in second life as long as you're not a griefer.
There are some fascinating places in second life.  NASA has a semi-official location in there, with info, models, video, pics, etc. of past, current, and future missions/equipment.  I think they also simulcast special events in there and might even have a live NASA TV feed running in there.
If you haven't tried second life, it's worth giving it a shot.  Costs nothing (IIRC) unless you want some property to build on.
