I used to play Final Fantasy 11 and got seriously addicted to that. In order to get anywhere though you HAD to be in a group, which took a while to organise. When you were in a good group, you just didn't want to leave which meant many late nights/early mornings. It felt more fun/social though.
Then decided to try Wow 'cos a few friends were playing it. Played my first character pretty much solo to a high level, and then about a year ago got a character up to level 80 as apparently "that's when it really gets good"...
....but I found it boring, repetitive, and the constant updates kept messing up the balance, resetting all my skills options (as well as changing how some of them worked so had to learn how best to do things again) and generally playing havoc.
PvP seems to have deteriorated into a "whoever has the best armour/equipment wins" contest, and getting such armour was a grind - then was made available in the next updates for anybody to buy (for silly amounts of money, which people just bought in real money transfers) and in my opinion was getting silly.
The fact that most of my mates who used to regularly play have given up was the final straw - I canceled my sub a few months ago.
Now trying Aion since it's launch, which I'm quite enjoying - although not got a character high enough to try out PvP yet.
The only thing that I've noticed that I would be vaquely interesting in in the next expansion is the ability to fly in the old/original areas, making exploring a lot easier. Don't think I'll be back though.
Never been quite as addicted since FF11 though.

One of my mates played loads on Wow and had several (if not more) level 80 characters..
