I think Perfect World is the best MMO there is, but instead of playing where F2P becomes "Pay to be any good", I've moved on to a really excellent private network of 3 different server choices. In the the one I play, you start at level 150 (and in 2 hours get to 200) of R10 gear, and can level up to a maximum level 400 (900 on another server!). There are GMs online 24/7 and the players are really friendly and keen to help. There are tons of events, and customized quests to adapt to the high level, and great PvP too. There are lots of players online at all hours. Oh, and I mustn't forget the customized flights and mounts, and the fash! This is the best server I've played on - ever.
