ill be honest and hope to help you as i am a MMO vet, played every one of them, and only just got on to this game. i played WOW, EQ2, SWG, GW, and DDO. wow and eq2 are the tops of my previous ventures in mmo work. but eq2 got boring early and wow, well WoW was fun until you hit lvl 50, and then it sucks, and the community sucked. kids or adults who simply wont help you unless they have a chance at gear.
here, so far, and im only lvl 8 And a week in ( cant play much due to work), but i like it a lot. the folks are all nice and helpful, a veteran MMO community. graphically, well, it isnt EQ2, but it isnt anything bad. the skill sets are tops of all the games, unique feel to each skill based on classes, above par animation, and you feel like you are actually developing a character class as opposed to say, an eq2 char where you're char shares all the archtype skills until late in game. here, you have a niche early. the availbaility of items for decent prices early is great as you can affordably upgrade all the time, maybe not to top lvl gear, but each lvl you can find something to upgrade and not pay out the butt for it.
questing is a bit weird, in that there isnt any map direction. i had 2 intro quests on hibernia, where i had to listen to ppl who i couldnt find, and another where i had no idea where to find the NPC and no direction from the journal. but the quests are pretty direct and fairly easy to find. even early on, there are solo ones, and other ones that should induce you to find some help. the task system is great and i cant wait to find the RvR material.
onto the big factor... the grind. not much i can comment on here. again, im only lvl 8, but if you are to wander out from a town, you are barely under constant aggro. but the sheer number of enemies to kill is great. better than eq2 which was tops until i played this. i hope to find some more puzzle type things to do, but who knows.
if you played MMO's b4, i suggest the furst thing you do is to get into the options and adjust the keyboard keys and shortcuts, as this game doesnt follow the proto typical command lines. but that is easily solved within 10 minutes and makes the game more rewarding.
