The problem with 'Morrowind vs Oblivion' debates is not so much what people say but how they say it.
I'm sure you didn't mean it this way and I'm not trying to pick on you, but this is an example of the kind of categorical, 'opinion-stated-as-fact' way of phrasing a position that tends to get on the nerves of Oblivion fans. It is this, more than anything else, that puts such a chip on their shoulders.
I hate to say it, being one myself, but Morrowind fans are the worse thing about Morrowind. They tarnish the very game they hope to promote. This primitive 'I'm right, you're wrong' attitude does Morrowind no good. Human beings do not like to be told that their opinion is wrong, that their opinion is less important than someone else's opinion. This manner of speaking is not designed to open up debate, it is designed to shut down debate - and that makes people angry.
It seems to me that gamers are particularly prone to think in stark, black-and-white, either/or categories ("This svcks," "That rocks"). Instead of saying "I prefer Morrowind," or "I think XXX feature of Morrowind is better than XXX feature of Oblivion and here's why..." gamers are too often prone to state, bluntly, that Morrowind is better than Oblivion.
Again, I'm not criticizing you, Troyatz. Actually, the reason I quoted your post in particular is because it is an example, I feel, of how this manner of speaking can creep even into the best writing. I'm sure I must have done it myself, more than once, without realizing it. But if we are ever to have a genuine dialog on this subject we need to learn to express ourselves with a bit more care.
