Claudia is right, I was lost in Fallout 3 land for quite some time but got burnt out on it. I'm itching to play my first full playthrough of TFN and write down ideas that I get to make it better. I'm starting to get that tiny burning feeling to mod and fix bugs so an update may be released in the next 6 months or so, we'll see.
TFN is actually built on top of CE 1.2 which was built on Wesp's patch 6.5. Any bugs that 6.6 or later addressed that pertained to TFN were implemented however I didn't blindly merge TFN 1.1 with Wesp's patches, they are independent.
So when you play TFN 1.1, you're getting Official Patch 1.1 and Wesp's 6.5 Patch along with many features of CE 1.2 (minus the things that TFN changed obviously).
