I want to die by a mini nuke. What I dont want is getting nuked out of nowhere randomly.
My favorite enemy in Fallout 4 and maybe my favorite enemy in all fallouts, is the super mutant suicider. They represent a threat at any level, they always kill you if you decide to ignore them, they run at you, they warn you, they raise your tension, but if you fail you die. Fighting them is fun. But getting nuked out of nowhere is not, you can't even be prepared for that unless you have died to it already, I consider that really cheap, unfun and overall a bad design choice.
What? dogmeat can open locks? wow I didn't know, the other things about op weapons early on, I am not sure if I want to try that amount of meta gaming. I heard people playing on survival from the start and spending more than 100 hours in that difficulty, I doubt they made it using guides and metagaming, or cheating to get op gear that way. But I simply don't think it was easy, unless the concept of easy has really changed with the time I see a lot of challenge on it personally.
