Responses like this and even the OP 's title says it all. Most people today that play just want to play the exact same thing for some reason.
People play "any MMO"
People get tired of it and talk about "New MMO" coming out, building it up
People play "new MMO" then get mad because it isn't like "any MMO"
Get on forums and cry.
You can go to ANY forums on any MMO and they all look like this. Maybe the problem isn't with the games, maybe the problem is with the players.
