I didn't even notice that there was a limit while playing the game. But now I google new vegas and see that many conversations had a lot of dialogue options, far more than four.

It is sad when a game needs extended scripting and mods to actually be what it should have been from the beginning. To be honest, seems like Bethesda is focusing more on Doom Eternal due to Doom 2016's success, a more competative action packed game wit hbrutal mechanics and more tends to win over the games that keeps lacking on things.

But! On the other hand, a game that has everything from the start gets boring after a while anyways, at least thius way, you'll get to see new shizz being created that keeps the game alive a bit longer

All Bethesda games seem to need modding to be what they should have been. Even New Vegas needs mods to make it closer to what it would have been had it not been held back for the consoles (like an open vegas.)
Bethesda is also _horrible_ with pacing, putting things that would normally have been late content material right in the beginning. Power armor and a deathclaw in what amounts to the tutorial, killing a dragon at second level (something that is a big deal in most fantasy games but becomes a trivial nuisance in skyim.)

I know what you mean.... There is no sense of achievement to aquire a PA right fro mthe start... I try to avoid starting the Minuteman questline til a bit later atleast... I could also say the same about Fatman... You can get that pretty early too, which would seem a bit stupid, its as if you would get the BFG right at the beginning of Doom... So I tend to pretend of not seeing it, even though its tempting to pick it up just to cause mayhem.
