No worries, you were clear enough in your posting that you are simply bringing up points others have made to tackle some aspects of what I was pointing out, perfectly reasonable to do (and you flat out admit that you are in no means trying to project those sentiments onto me). Now, to address something you brought up that I think it is important to point out - not once have I said that these games should be made exactly as they were 15 years ago. In fact it is quite the opposite where I have stated all the newer games have done their own great things. Let me specify some, though not take the time to touch on all, more for the sake of clarity:
FO3: 1st person perspective is excessively immersive and was a good thing to consider (something the original devs were not doing to my knowledge, even with the canceled Van Buren), I like that RPGs can try to leverage this medium. Also the move to real time combat was a very good move, something the canceled game was known to be attempting as well. Hitting a new part of the world and getting us out of the West Coast only vibe was also good, and left great room for coming up with new factions and the sort to further build on concepts that already existed.
FNV: Adding in things like Challenges, gameplay modes (hardcoe - would have loved to see some other ones as well), and putting a bigger focus into crafting and scavenging in a blasted out shell of a world. Stepping away from the black and white, good or evil troped that Bethesda has been known for and opening up a range of possible outcomes was also clutch.
FO4: From what we have seen so far, the enhancement of how armor systems work is a step in the right direction as it provides that cobbled together feeling of the post apocalypse. The enhancements to crafting and modding of items and structures is also a fantastic enhancement.
All of these things are still Bethesda taking the line in new directions without detracting from what was already making the series a great thing. My concerns are when systems get scrapped whole sale for reasoning that is really shaky at best (the arguments that are levied at the Skill system are fantastic examples of throwing the baby out with the bath water). Things that fundamentally change the way the game is handled and presented at its core. Series get the acclimation that they do based on the things they do right consistently, and I just don't feel this is one of those changes that was actually needed when they could have just patched up what they had already given us across 4 other games and got us into the groove of.
To put it comparitively, how would a reader of a series of novels feel if suddenly some 3 novels in the writter decided that some fundamental aspects of the way they handled things in this world were going to shift. It changes everything about the line in one fell swoop because that sense of continutiy has been shattered. If these changes are as arbitrarily approached as something like this it is even more jarring and grinding on those who fell in love with what the game line has always been about.
And I will point out that I have taken your stance, I don't buy products I am not about. I tried out Skyrim on a friend's copy and was able to conclude I did not like what was done with the game and thus have not invested money back into Bethesda by buying it solely because it is an Elder Scroll game and I love that series. I object to the way the series is going, and it is not the game line that I fell in love with so I don't buy the product. I will approach FO4 the same way, but like many other I am not decided on my stance at this point. I don't know enough about the game for a concrete stance - but I know enough that I am able to articulate my concerns. I also know that by not voicing my concerns and just not buying the game will not result in anything working out for me either. If the developers don't know why I didn't buy a product then they can not take steps to win me back with the following product.
Again, as I have stated, I am not shocked that Bethesda has taken this route, and again with what they have done this is the logical path for them to take. Further considering that their desire to build anything like a classic RPG is nonexistent these days, with a focus on Action Adventure and toning down the layers of interactions. Again, that is all well and good, and they will find a perfectly good player base by making these products in that fashion. I am also not, once again, decrying the games as failures, looking at their sales figures alone proves that is a nonargument.
Now, on to your biggest point - you are correct, Bethesda bought this IP wholesale and has every right to do with it what they want to do. Changing the game from its core tenants is something they are totally in the right on. I just feel this is the wrong way to approach thing.
Let me add some additional spin on this. Fallout, the series we are discussing, has had spin off titles in the past. Fallout: Tactics is the primest example of producing something fundamentally different from the core line without stepping on the toes of the core line. Bethesda has, technically, continured this tradition by the fact we have gotten Fallout 3 (main line sequal), Fallout: New Vegas (spin off), and now Fallout 4 (main line sequal). What is telling to me here is the fact that of these 3 modern version, the spin off of New Vegas was the truest to the original content. I feel like there is something fundamentally wrong with that approach, personally. The core series should keep to what it is, evolving and enhancing as it goes but not massively shifting itself from what it has always been.
Anyways, I think across my multiple posts in this thread now I have been as clear as I can possibly be about the topic. Though I will happily still debate any new key points leveled at me directly, I don't presently think there is much more I can say on this topic.
