My story is pretty much the same as most posting here. I played during Open Beta (Hell, I may've played near the tail-end of Closed Beta, I forget: it was awhile ago.).
I *wanted* to sign for a month afterwards, but I didn't. I generally liked the game, but felt it was missing "something". Maybe it was ground combat (although I heard it is better now). I think people were comparing it to Eve Online in terms of a "time sink" and I could see it. Not the PvP persay, although losing would be one, but the Trading/making commodities and the Auction House.
Such things are fun for some players, but I wanted more action. Also, I really didn't find a guild. I enjoyed the particular international servers (such as the French-populated one). It also seemed, to me, that if a particular nation.guild really got hold of a particular server, there was very little an individual player, such as myself, could do about it. True, I probably needed to join a Guild, but I am still looking for one.
I know it is an MMO, but it didn't really seem to be too fair to a single player. Sure, I could avoid conflicts and be good in a fight, but after awhile...meh. Still, I love the setting. I may try it out again..."one day"...
