I have played the "MMO Revolution" and I am bored. I don't really see the appeal and the argument usually dwindles down to THIS GAME HAS NO MONTHLY FEE YOU CAN'T HATE IT ROAAAAR.
Character progression feels thin, world events are just Rifts (success depends on how many ppl are there) and quests are just veiled behind the heart system. It certainly keeps me feeling busy but the core gameplay mechanics just don't feel fun. Seriously, I'm really really trying to like this game but it just isn't clicking with me
