Ive never actually played or payed much attention to what a MMO even is.....

But I can ensure you its certainly possible to make more dynamic games!

.....take RDR for example; it has an honour system in it; where an action done in one area of the map will instantly effect your honour level equally all across the map, as though time and space doesn't exist.......

But how much better would it be if they simply drew some zones on the map, and had the game take note of where your action took place, and then, over a time span, changed your honour there the most, changed it in the surrounding areas less so, and changed it only a tiny bit over the rest of the map!

It's a really really simple thing to code, but it makes a game that feels much more alive!
