Got to add my admiration as well for FDEV.
The networking instancing/island/bubble part of the engine is no small feat to get working and so far since SB1 I have had none of the huge waits in HS and SC to normal space that I had previously in PB.
Performance also seems improved, but I'm not telling the wife that, as I've convinced her that I need a 4790K/Maximus VII/GTX780 upgrade
Everyone I have shown PB to (not had a visitor/guest since SB1) has admired it for looks, sounds and gameplay and some of my friends are a tough crowd.
