Elder Scrolls Online has all real 'gamers' in a hissy fit over how bad it is. Just watch Angry Joe's review of it and you'll be glad you didn't buy it.
WildStar seems pretty neat and is a bit untraditional but I personally do not think it will last and to be honest I do not like its style.
FFXIV.. I don't even like the Final Fantasy series but I know it is a great game because it has the same thing that made FFXI great, the players. FFXI thrived for almost a decade simply because fans of Final Fantasy liked it. Lots of those players were adults too, not the 13-19 teen age group that almost all AAA games seem to target. Now throw in the customization, the graphics, the gameplay, the music and everything else on top of the community. It is not going to die within the next five years, even if it sucked the fanboys/girls would keep it alive.
Final Fantasy is literally the Call of Duty of RPGs. People keep saying X game will die, Y game will be popular, etc but in truth Korean games haven't killed WoW, there's barely any polished MMORPGs worth mentioning and there are dozens of in-development indie MMOs that swear they'll be better than sex but none of them have delivered.
I kind of wonder how anyone can pay for a game like WoW. When they introduced pandas they played on kung-fu panda, a children's movie. As in they were trying to bring in children.. yet lots of immature adults play it.
Other than a few decent MMOs like FFXIV the current state of the MMO gaming world is absolutely sickening.
