Everything is relative Gizmo my friend and subjective to your own personal tastes. Naturally, we've had this conversation many a time before and the best result that we can ever hope to get out of it is agree to disagree or in the very least respect each others' opinions on this subject.
Plainly put, people look for different things and get different satisfactions within the same activity. I fully understand your pov about why you want Fallout to remain in the same format as it always has been and what are your grievances with F3 as both a Fallout title and named sequel, while I believe you understand my differing perspective as why it is both a worthy sequel and game based on my own judgment.
I've often quoted different games which have altered their gameplay structures in order to "modernize" their titles or in the least reflect what the audience looks for during the times. Resident Evil and Metal Gear quickly spring to mind as examples of games whose core gameplay were altered and gained, not just exceeding success over their predecessors, but high critical praise for these changes.
F3 is far from perfect, in fact many of the shortcomings you criticize are those I myself agree with; mainly the elimination of choice/consequence and the watering down of the story; mind you I by no means agree that F3's story is bad or even poorly constructed as others express, I merely would have liked to see it expanded and the characters even more when judging against the stories of games I find much more developed such as Mass Effect.
This said however, I also have to comment that I don't find the original Fallout titles' stories to be that grandiose either. In fact when it comes to dialogue with Fallout and Fallout 2, I'm quickly reminded of a Beth title which often shares favorable nostalic evaluation: Morrowind. These games are often praised and heralded as being masterpieces, as some might argue, particularly when compared to the current iterations of Oblivion or Fallout 3. What I found after actually playing these games was that in fact they were hardly that superior at all to those they were being compared to.
The Vault Dweller's choices of dialogue were more developed and certainly hilarious (Oh that line about the sandwitch makes me giggle to this moment); but take just about any other character in the game and what you'll find are watered down and generic quest givers which offer a little information about the town you're at, the mission at hand, and maybe if you're really lucky of their background. The conversation I enjoyed the most in Fallout was with Harold because I felt he was the only real character outside the Vault Dweller who was given any sort of depth. Take anyone else: Aradesh, Tandi, your namesake, Killian, Ian, Decker, or whomever and really examine all of their dialogue and you may find what I mean. I find them about just as ordinary as any npc in F3. Chose One and the npcs of Fallout 2, the same.
Morrowind, oh my God how I was bashed over the head about the genius that was Morrowind when compared to the dull lameness of Oblivion. So I sat down one month and a half with the ES3 GOTY edition and played my way every quest I could from Vvardenfell to Solstheim and you know what I found? Exactly the same result as Fallout. Sure, I enjoyed the 10 minute long conversation with Vivec who was so rich in character that I hardly wanted to leave but everyone else...from Barenziah to Helseth to Dagoth Ur, they were just ordinary as characters. The wealth of Morrowind's richness lays in the background lore found in books. But all in all, their npcs were just quest givers with a little or no more to say much like Oblivion's; and in fact Oblivion's way of transmitting lore was simply altered to conversations instead of thousands of books thrown about everywhere, not diminished as most claim.
I really enjoyed my time playing Fallout and Fallout 2, I find the worlds intriguing and the settings are top notch because of the ideas that they represent. I find that this was translated well into Fallout 3, even though the fundamental gameplay was changed, and in fact altered to a preferred method of playing for me. When I'm playing a game, I like living the experience that the character is having; I like being the character as opposed to observing him like I would do a movie. Perhaps this is the reason why I enjoy Fallout 3 more; the Vault Dweller's journey was entertaining but somehow disconnected for me as I was more of an observer...I was recounting his journey but it was still his, with the Lone Wanderer it was my journey through the Fallout universe I experience because I am the Lone Wanderer and experienced the journey through my eyes.
This is the reason why I selected Fallout 3 as my favorite game. Nevertheless, in a strange way, I honestly feel that because they are so different Fallout 3 and its predecessors actually complement each other very well, the same as I feel about Morrowind and Oblivion.
PS Hope to see some more progress on that [censored] Enclave armor Gizmo, it rocks! :foodndrink:
