I think that long intermission that I had while trying to look for something else to play (but at the same time...wasn't so time consuming) failed in that every mmo that I've tried so far feels like they just slouch on the story... or if they did try something, they just give you a wall of text. (I like mmos where the storyline could be given in dialogue form.)
TERA is a fine example...it had a nice combat system, but the story, and the way it was presented, was horrible. After getting to level cap, there was nothing to do. I don't remember any of the NPC names in the game... not one single one. All I could remember where these three groups and some dude named Kelsaik that wanted to do something to the world in TERA.
NWN, let me tell you, I stop at about level 6-ish. Felt like I have to pay a little bit of this or a little bit of that for just about everything.
The action-types are great... as long as they could balance it out with storyline, otherwise I get bored easily. TERA was fun in that there wasn't a need for point and click. I could solo BAMs with enough concentration.... It is definitely a different experience than point and click mmos.
