Well how should I put this... Some more constructive criticism would be nice. I do have a number of problems with Bethesda.
Removing attributes.
Oblivion having no conflict between joinable factions.
Skyrim's main story- many things about it, including just how fast you become special in it.
Skyrim's quest lines being so short.
Skyrim being so easy in general, and Oblivion being so easy at low levels.
Oblivion's overpowered clairvoyant guards.
On top of removing attributes, making stamina effect carry weight and have no effect on magic.
Making stamina less of an essential thing with each TES game.
Getting rid of levitation and especially acrobatics.
Getting rid of teleport spells.
Getting rid of digitigrade Khajiit/Argonians.
No underwater combat in Skyrim.
Not being able to join the Forsworn or Thalmor, and the Thalmor not being fleshed out enough.
Making Daedric armor much easier to get.
Enemies never interrupting your rest and attacking you while sleeping in Skyrim.
Removing durability from Skyrim.
Making smithing improvements more important than weapon materials for damage or defense.
The majority of how the perk tree was handled in Skyrim.
Making things like Skooma have less dramatic effects.
Making enchanting so simple ever since the end of Morrowind.
Closed cities in separate cells than the surrounding world.
Not keeping Michael Kirkbride around for writing. (Big one).
Making regular attacks NOT consume stamina.
Imo gutting the magic system ever since the end of Morrowind.
Getting rid of normal weapon resistance/immunity.
Making each TES game more scaled via level.
Less types of weapons after Morrowind.
In vanilla only one joinable vampire clan by default ever since Oblivion.
Less factions after Morrowind.
What Skyrim did to mages, and nearly everything about Skyrim's magic system.
And hugely the decision that EVERYONE even random commoner NPCs need to have EVERYTHING voiced. Which I feel like with both modern and near future technological limitations is toxic to Elder Scrolls games, because it makes modding much more difficult, and it means there can't be as much spoken content by the characters for the same amount of effort, data, and time as dialogue only. Not to mention the data bloat it causes. With modern technology if everything in Morrowind had to be voiced for instance, it would probably be too expensive, and even if they could afford it, they couldn't spend as much effort on other things, and the data bloat may be too severe for it to run on most computers anyhow.
I'm not all out anti-voice acting- such as voice acting for say big lore bosses or for basic greetings, but I'm anti using voice acting for EVERY SINGLE LINE OF DIALOGUE in TES games, until we have sufficient enough future advances in technology, that make it where that doesn't severely limit how many things NPCs say, and doesn't severely limit Bethesda's development time and budget. All those complaints aside... I love and adore Bethesda, I'm highly pleased with what I know about Fallout 4, and I've been learning a great deal how much better Skyrim's Creation Kit is compared to Oblivion's and Morrowind's. I am a widely outspoken critic of many things I love being removed from the newer TES games, but I always am explicit about what I criticize, so that it is constructive criticism rather than just plain criticism.
The Skyrim Creation Kit has a very good keyword system, replacing and manipulating objects is easier, spells are much easier to customize, I'm extremely pleased with the design of Skyrim's Blackreach, the vanilla object statics are very good, Skyrim's crafting system made modding much easier, Skyrim's AI is phenomenal compared to prior TES games, Skyrim has more factions than Oblivion AFAIK, Shivering Isles was a great expansion, Bethesda made the incredible Dragonborn Expansion, Bethesda released Dishonored, and brought jetpacks into Fallout 4 after so many of their games severely lacked vertical exploration, and now they're even giving Fallout 4 a hardcoe mode.
As for Bethesda not talking to their fans and being tight lipped, well something I think you should know is, Bethesda actually apparently even got death threats when my favorite TES game- Morrowind was released... From some fans after Morrowind's release. And that afaik is a major reason they don't talk to fans very often, which imo is totally understandable. Nobody should be forced to remain in contact with people who treat them that way.
If they were more talkative during Oblivion's development, then I'm guessing they finally had enough vitriol from certain fans, which I can totally understand.
As for me, while many things I described have disappointed me about Oblivion and Skyrim I have trust in Bethesda. Fallout 4 makes me optimistic about the future of TES games... And Skyrim's Creation Kit has allowed many great things, like Chesko's Frostfall and Requiem.
