Care to explain why, perchance? I really want to know, because I really don't understand it.
I'm going to assume that you did not play any of the TES Travels series, but you do not seem to object to the lore development therein (little as there was), nor do you abandon the genre because they exist. How would an MMO be any different? You could avoid it, and if you really, really hated what it did to lore (note: MMOs are not by their nature some sort of anti-lore) you could just ignore it, like many people do with the lore of other TES titles.
You make many good points.
My point, however, is that I don't
want to ignore TES lore. I want to immerse myself in it. I
don't want to play an MMO. Therefore, I want to experience the lore in a game I'd enjoy playing. A MMO would not satisfy that desire. In all honesty, my reasoning is purely selfish. I understand that there are many people who would love to explore Tamriel with their friends and rivals. I'm not one of them, and I (quite selfishly) hope that TESV comes as close to my personal expectations of it as possible. That may not be realistic, but it's how I feel.
