Oblivion wasn't that bad. They streamlined things and it sucked to lose features but in the grand scheme of things it was a collective step forward. Skyrim turned the streamlining to 11 and it showed in sales with normies slopping it up, I cede that one. Fallout 4, while being the single worst story Emil has ever put to paper, was arguably incline over Skyrim. They seemed to learn their lesson and toned down the streamlining. I'm not even going to bring up the dumpster fire that is 76 because TES/Fallout Bethesda had nothing to do with it outside of the initial world building. Clearly from what we've seen in Starfield it's further incline from Fallout 4 because the gripes most people had with Fallout 4 don't seem to be present anymore.
Oblivion was bad though, they scaled down what the original vision was going to be, RadiantAI never worked, the story was a total cop out (hence the emperor dying at the very start pretty sure he was meant to have a much bigger role in oblivion), the level scalinging ruined everything and the removal of spells and skills from Morrowind made it an inferior experience over all. Fallout 3 was very much Oblivion with guns, it took Obsidian to see its flaws to have come up with a version that was superior in New Vegas, removing the level scaling, emphasis on non-linear storytelling and just overall returning fallout to a somewhat closer attempt at its roots than Bethesda could do. Skyrim was an Arcade game in comparison to Oblivion, you gutted everything and turned it into an action game, Fallout 4 made it even worse by destroying the dialogue and revolving the entire game about scrap and settlements where Fallout 76 didn't get the memo and made it even worse by taking out the quests and NPCs. Starfield is more in line with Fallout 4 but you've gone back to Skyrim/Fallout 3 like dialogue trees and perk systems. I'm not impressed by that.
Are we really going to applaud them for walking back the stupid decisions they made from Skyrim onwards? come on. Maybe if they walked it all the way back to Morrowind and Daggerfall I'd see your point lol
