So I was thinking. Currently when we level in Warcraft the story is all mixed up. We go from Deathwing being the evil guy, to Illidan, to Lich King, back to Deathwing, then Garrosh, then Iron Horde... It's all jumbled.
So what would be your opinion on an MMO with a constantly evolving world? For example. There's a patch where Bob is the enemy. We get new dungeons, new raids, new enemies to fight out in the open world. But toward the end of the patch when Bob is defeated, the world reflects on that. Content related to him will no longer exist. Quests won't revolve around him, a dungeon where he imprisoned the innocent has been liberated and may have even been turned into a new friendly location, and the raid which was his evil lair is now in ruins. Gear that could be obtained from it is no longer obtainable, as with mounts, and other items. Then Billy shows up is trying to do a better job than his brother Bob. So new quests, dungeons, raid, locations will show up and the story progresses.
So going back to WoW, if they did this content which existed in BC wouldn't exist. Sure there'd be tavern talk of the days past, but there wouldn't be any quests related to killing Illidan or soloing Kara for old gear. It keeps the story up to date and no issue as stated above of the story being jumbled as you make your way to max level.
Would you play an MMO like this?
