Give people something and some of them will complain about. Some folks just can't be satisfied. The game is fun. Story is the typical MMO story which is pretty good. I'm not going to spell it out here cause I'm not about spoilers. Complaining about same old thing gets a bit on my nerves.
World of Warcraft: Kill 10 pigs, bring me 20 backs of useless stuff, or do this dungeon 400 times for this piece of epic gear that will be useless in 6-8 months depending on when they release an expansion.
Rift: The grown ups version of WoW, and in my opinion a lot better.
Eve: I have no clue cause I don't like spreadsheets but I can only speculate that its as soul sucking as WoW. Might be awesome though never know.
Guild Wars 2: WoW rinse and repeat with shinny stuff
Aion: WoW rinse and repeat and flap your wings occasionally.
The Secret World: Besides Defiance, TSW has been the most fun I've had with an MMO in years.
One of the 40ish Korean Made MMOs: WoW rinse and repeat without Pandas, but maybe a Raccoon or 2.
Moral of the story is MMO's all have a rinse and repeat style because without repeatable content people run out of things to do. I think Defiance does it right by having all the random things you can do to keep yourself entertained. Sometimes I take a break from working on websites and studying for exams to shot some stuff in the face. If they did promise content and it hasn't come yet then guess what, there was a problem, there is always a problem when your dealing with an MMO, it is just the nature of the best. WoW, the grandmaster of MMO in some peoples eyes for some reason that is lost on me, still has bugs, still crashes on occassion, be it rare, and its older then dirt. Oh and it puts new content out maybe once a year if people are lucky. And this game has just as much content as that terrible pile of shtako, Vanilla WoW had. If your expecting content on the level Vanilla through Pandas then you are a terrible person and should smack yourself. Just a little one not a big one cause that would be terrible but go ahead and smack yourself a little.
I've played this game for about 20ish hours of gameplay, maybe more, not tied into steam to keep count, and I haven't finished the main story and I still have about 20 or more side mission to go back and do. I haven't even done the second mission in San Fran yet. So again I say, plenty of content, way to go Trion you are doing an amazing job and don't listen to any of the haters.
