Son of a bitch, I literally just made a Fallout 4 thread. Well, shit.
The new companion, Longfellow, is boring as shit. He doesn't do much. The hacking of the mind thing was also a massive waste of my time. I think a huge issue with the game is it fails to commit. It's not funny like Old World Blues, or scary like Dead Money, or Lovecraftian like Point Lookout. It tries to tread a line between all of them, and I don't think it does it well. Still, as for actual content, the game was lacking for its price. There were a bunch of quests, but most of them were just "Go here, kill everything there!" They'd just give me a place to clear and a reason why, and that was it. Most of the map was barren and boring.
Still, there was a lot I liked about it. I liked the multiple endings, it was a good boost, though. I loved the new Vault, I liked the actual Far Harbor and DiMo, I liked the few new creatures even though there wasn't many. The plot itself was fairly interesting.
