Seeing as New Vegas is basically on the same engine as FO3 (I assume...), could this mod be ported or maybe even include more things if you decide to use the New Vegas G.E.C.K. (Which I also assume will be made available...)
I think it would be great to do all that Circus Circus Cockroach madness stuff with New Vegas. The GECK is virtually identical...and .lip files don't need to be imported from the TES Construction set (which is why all this is taking me so long).
