I think that all MMO's (if that is even what this is) are the worst kind of games in existence. This isn't because the games aren't good but because there is no end goal.... the game is never over... and that is just the way games are now. There's a certain addiction that a person gets to games like that which would never exist in any other format.
I played them for years, now I avoid them, not matter what people say.
I get what you say about MMO's but trully depends on the players point of view. when I was younger I used to love playing MMORPG, the "never over" aspect of the game is what hooked me so much. Now I see that there isn't much sense into dumping countless hours to the game UNLESS you like it very much!
