Yeah. It's in all ways a worse Fallout game than even Fallout 3. It is absolutely terrible as an RPG, it has a shitty story and is generally as wide as an ocean and as shallow as a puddle. It has a lot of good ideas, and all of them are executed so half-heartedly it hurts.
But the gameplay loop of going out, finding settlement places, killing a bunch of shit and connecting your places is more fun in itself than anything Fallout 3 had to offer. I enjoyed Fallout 4 as a mindless time waster. With We Are The Minutemen and Sim Settlements it's mildly fun.
Thats more than Fallout 3 ever did for me, because not only was its writing just as offensively bad, it also played like shit and no mods could fix that for me.
