The question that should be asked, though, is how many people were actually working on it for those 2 years.
With the amount of content there, this would be embarrassing for a professional modder to release in over 2 years time, more like 6 months tops. That's right, this is the kind of content one guy is capable of producing, so if Bethesda had a whole dev team working on this? lol, lmao even
This isn't professional content, just Creation Club tier "Go here, kill this, get this extremely overpowered weapon that breaks the balance of the game" slop, not actual quest content or new story branches that "next gen" label would imply. Gun Runners Arsenal for New Vegas wipes the floor with this, even if it does cost a small fee. BTW the Enclave content(the "main attraction") such as the Hellfire Armor and the Incinerator has been available either on Nexus for free or on Creation Club for years now, barely anything is actually "new" about any of these weapons or armor. They could have just repackaged some existing mods and call it a day, but they fucked up even that.
Compare the Enclave "quest" in the update to something like America Rising. Then let's remember that modders actually release game sized total conversions regularly(see the ones in chart above), this is humiliating across every metric for Bethesda even if they had one intern working on this in their lunchtime. Fallout Nevada/Sonora has been done by one dude in Siberia and it's arguably a better Fallout sequel/prequel than anything Bethesda has ever done, that's not counting every other project that has been released or currently ongoing.
I've seen theories in the Starfield thread that the reason they aren't releasing modding tools is that so the modders won't fix the bugs they are trying to market for their upcoming 2.0 patch(lol) like major bug fixes and buggies/vehicles(that were probably cut out of the game). This is exactly why they're doing this, so that they won't get humiliated by the fans who know the engine better than actual Bethesda does at this point or beat them to the punch in releasing some basic armor/weapons.
