I'll just chime in here, but considering the horsepower of the above posters I'm sure I'm out of my depth. I would love to be able to use MO straight from the start of FO4, but given the current limitations mentioned above, it is unlikely. Now... does Tannin have some big announcement upcoming? My heart would love to say, "YES, PLEASE!" But, my brain tells me that just like the guys at Silverlock.org, he has to wait to see the game files/structure fully before work can begin. So for the time being, we'll have to "make do" with NMM.
