@Sardinar You can indeed play it in isometric view. Its camera is flexible: you can zoom in and out and even adjust the angle until it's exactly like the original RO.
Sometimes I preferred to play in the aforementioned isometric perspective to easily overview the action that's happening (I'm a priest you see~ Mostly during party-based boss battles)
Other times I can play in Third-person =) (when leveling alone)
Now just lack a FPS perspective (like Skyrim's flexible TPS & FPS perspective)
