So uh....

ROSE is made by gravity.
gravity made RO.
RO is superior to rose.
RO2 is superior to rose, since rose is tailored for a younger audience.
the thing i like about RO2 is the pose-ability of the models.
and the fact there's a possiblity of custom meshes for items.
And there's a rumor about controllable guns for the gunslinger class.
