Of course you're criticized for liking the game. People jump down your throat all the time. I'm not even allowed to say it anymore as it's depressing how much flack you get for even stating that you like the game.
Of course there are things in the game that are off, or glitched, or I have issues with, but, I chose not to criticize. I've played Beth games since Morrowind and all of the Fallout Series as well.
IMO - yes, there have been changes and adaptions to the current needs and wants of the gaming population as a whole. Certainly those hardcoe gamers that want difficulty modulations or do not want simple mechanics that anyone can understand will not like certain aspects. Certainly, in some cases the story and the "freedom" Beth so prides itself on have been narrowed in definitions.
Me - I love F4. It's my one an only shooter, just as ESO is my one and only MMO.
I don't say their perfect, but I focus on what I enjoy, not what, to me are minor issues that, in no way affect me at all. The MacReady glitch? To me, so what? I don't use companions unless I'm forced to. Never have. The exploits (unlimited caps, duplications, etc...) - I don't use them. Never have in any game I've played.
Would I like it if the Monsignor Plaza glitch was patched? Of course! Would I like it if the settlement mechanics were tweaked? Of course! Would I like it if the weird Brahmin and settler behavior, not to mention the teleporting raiders and break dancing supers were fixed (okay, I can deal with the break dancing Supers - that's funny), of course!
But I'm not focusing on that.
I love F4 for what it is, just as I loved Oblivion, Skyrim, F3, FNV, ESO and so many other games (DA:O, DA2, DA:I, DD:DA, SoM and so many more) for what they are. Flawed gems or, sometimes flawed pieces of [censored]. I just love gaming.
It's just my opinion. It matters to me. That's all.
