Everquest. First XML based user amendable UI in an MMO.
Warcraft while very good has never been overly innovative. It has however always been very good at polish.
Agreed. Blizzard has a policy of polski.. err, polish.. that makes them look absolutely anal. But that's only because the competitors fall way short. And it's all down to the way they design their game.
Most, if not all MMO developers throw land mass down in it's entirety. Then they go about filling in the content, with different teams working on different areas simultaneously, but at differing stages. Any break down in communication that happens between the teams inevitably results in a game that can at times feel very disjointed. There's other pitfalls to this but I won't go into it.
Blizzard do things differently however. They go from zone to zone, one at a time, and put the content in. When they finish with the first zone, after making it as fun as possible, they move onto the second. If the second zone does not equal the quality of the first, they hammer on it until it does. All the people working on the game are on the same page.
It might sound like an obvious approach, and one that all the MMO developers would do. But they don't.
Anyway, I'm not a WAR fanboy, nor a WoW hater. I think most MMO's are equally disappointing tbh. WoW is a fine game, but things like NPC's with pop culture names, naked gnomes dancing in Ironforge, the fact that it's a loot pinata (everybody wins in WoW, even if you suck) and the idiot playerbase put me off. WoW just happens to be the one on the pedestal, so it's the one I throw rocks at the most.
