I'm 39 years old and fell in love with the first 2 Fallout games as they were unique and provided game play never quite seen before. But I'm not going to get hung up on nitpicking the past.
I realize that you (Bethesda) had to stay as true as possible to the Fallout lore with the third game since it was a sequel to the original stories of the first 2 games. You made some small, but large improvements when it came to the 3d views and voice acting. Kudos!
Then Obsidian created a side-sequel that expanded upon the third game. What some people might not know though, is that Obsidian was founded by and made up of many of the same designers/programmers responsible for the second Fallout game. Barring some technical glitches, of course they did a great job with it, because it was their brain-child they were working with!
However, there are some major things that violate the Fallout lore with this 4h installment:
The protagonist talks... fully voiced and so on. This isn't a minor detail when it comes to an RPG, it a very large, very noticeably detail. We can no longer create our character's voice in our heads when you've already done it for us!
Our destiny is pre-determined. Although we can make a choice, our choices all lead down the same path and end up doing the same things. It's as if you saw gamers creating their own min-games in Fallout 3, got upset by them not "playing it your way" and decided to now, leave them no choice.
The vaults are social experiments.... Albeit, creative, you've just essentially flipped-off those of us who grew up playing this series. No, seriously... this is like a 16 year old kid learning that he was adopted when he was 2. If you recall the first game, the Vaults weren't necessarily bad things - people even founded post-war settlements around their vaults. Now we're led to believe they're some sort of government conspiracy-experiment.
You've also taken one of the most iconic pieces of the Fallout universe and handed it to us on a silver platter right from the get go; Power Armor.
I really don't think you (Bethesda) "get it" about the Fallout franchise. The protagonist has and never was meant to be an uber-curb-stomping-Deathclaw-killer right out of the gate. We're supposed to get our asses handed to us by Radscorpions for a while... a long while, before we are ready to get our asses handed to us again by a Deathclaw or shredded by a super-mutant's Gatling Gun. The fun was going back to those Deathclaws and super-mutants with our new "toys" and using them as target practice later on!
Crafting, survival games have been done. They've been done better and with more detail by games that are specifically designed to be crafting-survival games - Eg: 7 Days to Die. When you're making an RPG as detailed and complex as Fallout -should have- been, you don't have time or resources to waste on other features like crafting and base-building. Let the games that specialize in that, take care of that. The job of a Fallout RPG is to immerse us in the world of a lowly apocalypse survivor and let us grow with him/her over the course of the game where we get to choose who he/she is and what they do.
This game, although good in its own right, should not be called Fallout 4. Calling it that, feels like an insult to everything I knew and loved about the entire franchise.
