Ideally, the game should be playable in a web browser, to be reachable at school, work and so on. This does not make it impossible to develop a 3D client per se, but it would be easier to do so. This, of course, does not eliminate the need for creating characters, "monsters", structures and terrain in 3D programs; it would merely have to be pre-rendered.
