And where did I say or even implied that it is?
I just don't see the appeal of complimenting someone for doing the bare miniumum. What are we talking about here, a toddler who did his first steps or something? That's like complimenting a postman that he delivered your mail on time. Considering the fact that Fallout 4 is closer to an FPS game then ANY(!) other Fallout game in history, I would damn well expect a decent shooting mechanic, and not becoming hyped about the fact that well ... Fallout now plays like a standard FPS game. I can't really follow this sentient, I am not targeting you in particular, it's just that I read this often as a postive point about Fallout 4 when they talk about the game or even dare to voice some criticism. Like as when you visit a dirty restaurant with an stinking toilet, and they say, well at least the food you get isn't poisoned. The fuck?
You could take a look at Obsidian for example, which have been forced to work with Fallout 3s system and tried to improve it, in some cases they succeed in some they didn't. They tried to make a difference between the armor and amunition for example, they expanded crafting and made the game in general a bit more complex.
And Bethesda could have expanded on that in Fallout 4. But they really didn't, infact all they did from Fallout 3 to Fallout 4 as far as the combat goes, was to simplify it so that when you push the trigger the thing in your hand shoots till the enemy is dead. And thus making it closer to pretty much EVERY FPS game in human history. But there really is so much more that you can do! Take Deus Ex 1 as example, where many weapons had a different use, advantages, disadvantages, with different amo types and upgrades which even offered you a vastily different experience in some cases, as certain weapons had enough power to blast doors open.
