As someone working in the game industry, I can say that right now, even 
if we use fully use Boost in our tools, in our engine we use Boost with 
parsimony (typically libraries .hpp without .lib; easier to control code 
size) and also disable RTTI since the memory overhead is not worth the 
cost.  A performant state machine mechanism working without RTTI would 
be interesting.
