I really like mmo's and ones that really had a life to the world which was very open. I like the cryptic ones and they are sorta a good example as their stuff getting further from the mmo thing I like. champions had day/night cycles and like chinatown had fireworks in the evening an you could see the traffic patterns follow the workday and you saw the bussiness high rises lights go out as it got later and residential ones come on. It was real neat. STO only had day night on risa and they had to get rid of it with an update where now the time of day was basically different for different instances. neverwinter not only had no cycles like that but became much more on rails with sorta pho environment that was by and large just big long tunnels. I love customization in both character visuals and builds which again became more limited as you went through what you had. The big thing with mmos though is the online reliance. You have all these neat things but if the servers go offline then you lose it all. Would love an online/offline mmo with all sorts of options for look and builds and big open living worlds. As far as type of world I have a soft spot for superheroes as you can sorta do everything with it. magic. technology. and of course just powers. I just wish I had the time to get back into them.
