In the Fallout:NV GECK,
Why do I see GOAT questions!? (E.G. Fallout 3 GOAT Question 1: A mad scientist runs to you and says something that you dont understand, what do you do? A. Respond with a very intelligent answer, B. etc C. etc D. etc) Something like that..
Is it me or do you guys have it too?
If you guys dont have it, it means my mod that i ported over have ported over lots of unnecessary stuff...oh crap, how do I get rid of those useless junk?
DON'T PANIC!
Sorry, you seemed to have needed that. ^_^ You didn't bring over anything with your ported mod. Beth and Obsi left a ton of stuff from FO3 in the BSAs for us to play with. Since it's already in the FNV BSAs it's legal, you can use whatever you like. So there's nothing you have to worry about getting rid of.
Just one thing to note- not all of the FO3 stuff in there is complete. Some of it could be missing textures, meshes, sounds or animations. If one of those is missing, you'll have to make your own to replace it. You can't port over the missing parts(as I'm sure you know).
