I don't like 3D mmos, they tend to remove imagination, if things are HD definition, you see what you see, you can't guess what you see and think of it like you wish, in ultima online, seeing the floor of a forest leaf by leaf would remove the immersion feeling of the game. Just look at the home decorations that some people made, a blue cotton top fountain, a statue stand made with cookie plates, and much more would just look ugly, as they are not used as imaginative tools, but rather strict-use only items.
Caring only about the orthographic view is better, as it's a single image you can draw, as in 3D you need some programs to make those, and sometimes they are done wrong; using more poly, or has a texture inside...
Plus, people will go see that game but they will not trash uo forever... See it as temporary 50% time spent away, like any other game a uo player has...
