I never was interested in the Witcher series because of the absolutely fixed protagonist. So I don't have any experience with BGS. Well, DA:O had at least something that made it easier to actually add mods. It was also the most popular. If you look at the Nexus, the least liked game was DAII. DA:I isn't doing that much better, so far.
Well, Todd Howard said, the creation kit would come some time in early 2016. Whatever that means. But, I fear, since the hype is already dying down and since modders have a harder time with a fully voiced protagonist to add new content, that FO4 won't get as popular as FNV, which has over 16.000 mods on the nexus alone.
How is that any different from any of BioWare's fixed protagonists? Especially since Shepard, less and less control has been given to players when crafting these protagonists. I really don't see any difference between Shepard and Geralt, other than you can't pick his gender or alter his face. Otherwise, same kinds of decisions and choices in a BioWare game. Well, Witcher decisions are more nuanced being shades of grey instead of BioWare (good - neutral - bad).
I'm just saying there are mods for Dragon Age. I've modded DAO extensively and I even modded DAII as well. I haven't modded DAI yet due to just not having time, but I know it has a pretty robust modding community. I know there's a mod to allow female Inquisitors to romance Cass and it got a pretty big following.

What's truly ironic about your statement is BGS didn't even create FNV. Obsidian did! I love Obsidian. They make such great sequels (KotOR II, FNV), yet they are such an underrated studio.
