But WoW had plenty of content at launch. It has a lot more now obviously, but I recall no criticisms on that front. And WoW came out after EverQuest had been around for five years, but it wasn't lambasted for lacking content in comparison. City of Heroes had a good deal of content at launch, though nothing compared to what it would gain later. Heck, FFXI had plenty of content, which would grow and grow. FFXIV's will as well, but that doesn't mean that what is there now is sufficient, or that comparisons are unfair.

If folks like FFXIV then good for them, and as I've said I hope with time it does grow into a game I'm interested in. But this massive difference is clearly based on a lot more than just people derping and expecting a new MMO to have as much content and polish as one which is six years old, and "lack of content" or "limited questing" or just "repetetive levequests" or some such seems to be a theme across almost all the reviews.
