Can't really blame the game though, as I enjoyed all the parts of it that I've tried (except PvP of course rofl). Its only fault is that maybe it is too much like WoW, although in many, many ways it's much better.
Just didn't have the time or the urge to play a theme-park MMO. Enjoyed the quests, the dungeons / adventures, the challenges. Awesome combat, awesome housing, interesting crafting system, even the lore got me interested a bit by the end. I'd highly recommend it to anyone looking to try a new MMO.
There's plenty to do at level 50. The attunement process alone will keep you busy for at least a few weeks. Then you have the raids and of course crafting housing. There are plenty of achievements to try, challenges to complete, stuff to gather, so you'll probably revisit some lower zones as well.
Haven't tried Warplots at all, really curious how that will be, as the concept is very interesting.
Ditto what mynsc said. I spent most of May/June playing it and it gave me so much of the theme-park MMO blues that I lost interest. On top of that, none of my friends were playing and my guilds didn't turn out how I'd hoped.
But like mynsc also said, if you ever liked WoW, it's a pretty good bet that Wildstar will at least be worth the box price for you.
