Not just talking about the world but about the whole game. A huge world is good to me.
WoW has been and is still quite of a special game, and I really appreciate that they keep adding raids/dungeons/expansions, but I've just felt something weird, I realized the game is truly starting to be huge, at the moment it's alright, even though the game is massive, but what in a few more expansions ?
Do you think the game can be too huge ? Do you think there can be too much content ? How are other old MMO dealing with that, is it a problem for those games ? (I assume Everquest is very huge now, but I know nothing about it)
Personally I think they should use old content way more than that, timewalking is nothing compared to what they can do with it. They can possibly make all content current content, I bet an increasingly high number of players are not even seeing all past content, which feels like kind of a waste.
