I did not compare Fallout 4 to New Vegas but to the time it came out. Which is 5 years later btw. New Vegas had a compelling story telling and role playing while Fallout 4 could barely shine with some minor modernizations.
Fallout 4’s more modern gameplay? Oh shut up. They lost me right there. Not that i did not enjoy Fallout 4, do not get me wrong. But it sure is not modern in any way that counts. Quite the opposite. It already feeled aged at release.
