The voice acting and story were cool in the beginning for each of the eight roles to play. Maybe it's just me but I puttered out around level 20 for the 3 I tried. Just got bored, I guess the MMO "paint" underneath just started to show through. I had that happen with EQ, DAoC, WoW, and SW:TOR. The only MMO'ish games that I didn't burn out on right away was UO and GW (1). Maybe because UO was skill based and more of an open world, and maybe GW because getting to lvl 20 was easy and from there you just explored and got loot and skills.
I'd LOVE to see an updated (OLD SCHOOL VERSION) of UO.
