In hindsight, Bethesda should've stuck to their wiki-style "keyword" dialogue system. There was really no reason to change it, only to flaunt with thousand-and-one [skillChecks] and give the illusion that skill choices actually mattered.
They could've even tried to be revolutionary, and introduced a wiki-style dialogue wheel, enabling one to ask every single NPC about "Dad", "Capital Wasteland", "Brotherhood of Steel", "Enclave" and "Vault".
