For me if a MMORPG is good I usually will have some interest in it. At least the short term of trying it out and enjoying it for it's worth. For example themepark MMORPG I realized are just short term investments because the long term isn't something I am interested in.
When I play MMORPG that are bad I am not going to have much interest regardless of type of game. For example a game like Mortal Online if done well would have interested me. Unfortunately it was just bad to me.
But I always see if you want games like MO you must play it. I don't want games like MO because I found it bad and being the right type of game doesn't matter.
