I don't remember Rappelz ever being fun. When it was first released in 2006 or so the taming/upgrading/drop rates were absolutely terrible, though the population was pretty good since it was one of the better graphical F2P games at the time. Gameplay wise it was best about a year or two back ago IMO, I tried giving it a shot and I found the rates to be a lot better (which help given how inflated the economy was), but by then GPotato had already chased away a good chunk of the population. In any case, I never liked the dungeon system of the game - pick a room, camp it, grind monsters.

I did enjoy PWI and RFO when I first tried them (when RFO was with an NA publisher). The community of RFO was great.
