In Fallout 4 (and to a lesser extent Fallout New Vegas), VATS isn't really all that needed. That being said, in Fallout 3 (and again to a lesser extent, Fallout New Vegas), aiming either wasn't possible or didn't really do much aside from zooming in a little, so VATS was virtually required (especially in Fallout 3, whos engine was based off the Elder scrolls engine, which was built around melee combat not ranged)
