It's amazing how many of you JUST DON'T GET IT.
You love the game play, yet expect EA to somehow "fix the graphics" to make the game more fancy.
You don't understand that, in order to get more modern graphics, they'd have to rewrite the server code FROM THE GROUND UP, to interface with modern graphics - and in doing so, many of the elements of gameplay you so dearly love about the game will be lost in the process, because the new game engine won't work EXACTLY like the current one, no matter how hard you try.
The greatest failing of KR (and why it was so incomplete when released) was that they were trying as hard as they could to get a 2007 graphics engine to interface with 1997 server code, and the result was SEVERE LAG - not to mention having to dumb down the number of land tile types on the servers, that made many areas much plainer, if not ugly (see the roads, and tiles in Bug Reports that STILL hadn't been fixed in the EC as of current day).
In other words, the game would have to be budgeted as if an entirely new game, and even then the result would probably not be what you want - and the reinvented game would not be backwards compatible (other than importing existing items and characters, and even then much of that will get changed in unwanted ways - look at what KR did to home deco).
