I have played Everquest, Everquest 2, Rift, Wow, Swtor, and now A realm Reborn.
All good games. Some held my attention longer then others. Content is a biggy, but in any of them, you should take your time to enjoy the game, enjoy the scenery, and just enjoy playing them, or don't play at all! It's really that simple! If the only thing you worry about is getting to max level, you never really learn to play your character as well as someone who took the time to learn your characters positives, and negatives. You have to know your toons limitations as well as your spells. I have been playing for only a few weeks, and attained level 17, but more importantly, have enjoyed the trip so far.
