I think it's nostagia talking. Back when it was released...for the first year, it was dubbed the worst in the series. People finally warmed up to it AFTER mods. But if you have to mod something to make it good...was it good to begin with? I think MW was amazing, but back then people hated it forever...basically calling it Daggerfalls B****...on a good day (yes the fourms were that bad...skyrims reception is tame compared to MWs reception).
The definition of nostalgia is
1. A bittersweet longing for things, persons, or situations of the past. 2. The condition of being homesick; homesickness.What you'll notice is that those who liked elements from Morrowind aren't suffering the second, and that if they are suffering the first, then it is completely valid.
If someone changes something to make it perceptibly and definably worse (and the reasons are being presented all over the boards), and can present the exact points that make it bad, then they are justified.
Saying "it's nostalgia" and "this is better" isn't presenting an argument against the incredibly similar complaints all these people are having. As such, wouldn't it be necessary, therefore, to stop saying "nostalgia" like its some winning card and start trying to prove why making the game easier and less challenging is better (and doing so without falling into the trap of admitting you want to just hack things to death with your sword).
Similarly, people on the boards after MW was released weren't complaining about anything more than the combat third person inconsistencies. The complaints that absolutely dominated the boards after OB was released are exactly the same you're seeing here today. Fast travel and GPS. You'll notice that for these complaints to last FIVE years, they're pretty big ones.
Also, Morrowind wasn't dubbed "worst in the series" (please provide me ANY source that said this). Games that are worst in the series don't spark a huge modding community and legions of psychotically passionate fans. The mods have just given MW a playability, graphically and otherwise beyond 2002-2003. MW was an amazing game, and is an amazing game as a vanilla game, but it's also an amazing blank canvas on which mods were able to be made.
The answer is really simply to get rid of 80% of the complaints on the boards. Scrap or limit fast travel (why the hell do the carriages exist in the game beyond the first hour?), get rid of compass markers and the majority of map markers (especially for the bloody "ancient, hidden, unseen cave that is rumoured to exist, but I've marked on your map!") and you'll find a lot of happy people. And guess what, I bet that no new player would complain at all about being "forced" to actually walk across the amazingly beautiful landscape they've created, and you'd sure as hell satisfy all the old players who are sick of the default being "special school mode".
