Indeed, if people actually read the older threads of Oblivion they would see oblivion did get the same amount of "hate" and bashing as Skyrim does, except now it is Oblivion being the superior game, not Morrowind, I'm sure that Morrowind got the same bashing also for not being exactly the same as Daggerfall.
Actually, Morrowind got bashed for being so bloody damned small, compared to Daggerfall. We didn't even get the whole province, just the volcanic island part of it. And the majority of bashes were used on the console kiddies and shooter babies and their every third post of 'But if it were muuuuuuultiplayeeeeeeeeer...!'
At least until they created the MP thread and banished the clueless there to keep other threads from spontaneously combusting.
And frankly, the series has been degrading since Daggerfall.....which 15 years after its release, still has players and an active modding communuity (which has to write its own tools, btw). Arena was the 'simplest' in terms of CRPGing......yet it was innovative. You could go =outside=. You had a whole bloody continent to ramble upon. Sure it was limited in quest structure, graphics were 8 bit, etc etc, but it was something special....and at the time, unheard of.
Then came Daggerfall. Which despite the pulled features, deactivated options and endless march of causeway errors, earned GOTY back in the day when Ultima, Might and Magic, and just about every other classic CRPG series was alive and kicking. When winning GOTY was an accomplishment, not because you were the only entrant in the category. You were handed nothing; you had to work to earn every title. Sure you could power-game the systems......but you didn't have to. It had the most complex character generation system (particularly if you chose to create a custom character and accessed all the options).
Morrowind didn't get hammered nearly as hard as it could have been; most of the users knew that Todd & Co were stepping into full 3D for the first time. Then about halfway through he announced the dual platform development....which clued users knew would hamstring the game further due to memory and storage limits on one platform type.
Oblivion got slapped a bit, and justifiably so. The so-called center of the Tamrielic Empire was an outpost sized fortress in the middle of virgin wilderness........? You had undead infested ruins so close to said fortress that a guard taking a whiz off the paraqet could hit half a dozen of them without straining a muscle....and yet no sign of any undead on the surface, or knowledge of what existed withing whizzing distance among the citizenry? And so on and so on....
Then we get Skyrim, that masterful ode to "Oh, I'm gonna kill drago.....ooooohhh, birdies.....!"
Each iteration since Daggerfall has had fewer and fewer RPG mechanics and systems. The writing has similarly simplified. But the graphics have gotten pretty.....but only in the manner of a shooter; bling but no substance. Things never get fixed or improved on; just removed. And we'll be very, very lucky if next game isn't the equivalent of Sonic goes to Summerset Isle....
