Fallout 4

By the way, I agree FO3 was a little underwhelming. It too felt kinda empty, I never even bought the DLC for it. But I forgave it because, you know, first Fallout game for Bethesda and besides I was just happy to interact with the Fallout world at all (I had liked Fallout 1&2 and Oblivion, so I was pretty predisposed to Fallout 3 before hand)

Then New Vegas came out and I was obsessed. I loved the DLC for it, especially Old World Blues. which I had the good fortune to go into spoiler-free and kinda underleveled, so it was amazing. I know New Vegas wasn't directly done by Bethesda but I thought "okay, so this is where the franchise is going".

And when I saw that Fallout 4 had the same engine as 3 and New Vegas, I was actually a little excited. New Vegas was filled with bugs, which is natural with that much quest branching. I figured Fallout 4 was going to be New Vegas perfected. We'd finally "figured out" Fallout.

Instead it's like Fallout 3 with a crappy version of minecraft and an admittedly cool Mech-feel to power armor.
