Hmmm, was this a stealth stab response to my earlier post? At any rate this is why/how I think/believe MMO's are all fundamentally flawed, they don't end, its like an ongoing game of monopoly. They are meant to be long and grindy and just too cumbersome. I understand that if an MMO was to actually "End" there wouldn't be a point to playing, but this is where I find games like Diablo and Titan Quest great, they end, but you can still have fun after the game is beat.
But remember there is a semi-end to the game, that being "end-game" content aka raids, aka do the same skill rotation 9000+ times for several hours to let a random number generator decide whether or not the last several hours of your time spent were worth it. Ya.
But I will say as a disclaimer that the above statements are purely my opinion and is no way written in stone as facts. I'm just a shoot-em-up, RTS, fast paced person in the gaming sense.
