Well now I'm neutral about V21.  I love it, but I hate it.  However this could open up more realistic gameplay opportunities.  Splinter Cell DMs, working cieling lights.
I have a question though.  Will JVS content cast a shadow of the model seen ingame, or their ghost brick shape?
EDIT:  Just read Q&A Session one.  I know I might make myslef look like a total slowpoke, but what is BLB?
