I don't imagine it works like that, they're coders, you read the libs and put them to work - besides which they've had two years to become acquainted with it, I'm sure it'll be fine
I can't wait for this - I'm umming and arring about upgrading my GTX260 to a GTX460 for it, but worried it may be a colossal waste of cash.
They've had 2 years practice but most of that i imagine has been working on NV. Its not really the same as Bethesda who have a lot more experience with it from released games too.
The important thing is that they seem to have implemented a lot of the best ideas from the modding community. After watching a few videos, I think this has the potential to be better than FO3.
I've not really seen much of that, didn't someone say they'd added Weapon Mod Kits in? They were a great addition to FO3 but they didn't include custom weapons so if its done by default its more likely custom weapons will include them. Though it was sweet to pick up Ol' Painless to find it had a Scope and Silencer on it... made it 10x more awesome.
