I don't know how many of you, if any of you were hardcore WoW players. It's inevitable to compare every MMO offering to WoW because it's the king, plain and simple.
One thing Wildstar has going for it that no other MMO has had since WoW's release in 2004, is that Wildstar delivered a complete MMO experience on launch. It has a fully developed leveling system, crafting system, player housing, customization, a rich endgame, real raiding, battlegrounds, arenas... it's a complete MMO. That can't be said of any other MMO in recent history.
Virtually every other MMO is released too soon and is missing major parts of the game with promises to get better over time. Like SWTOR... awesome leveling, NO endgame on launch, and 2 crappy battlegrounds.
I think there's something to be said for a game that actually launches in a complete state, because unfortunately, that is not the norm anymore.
