Yeah, it has more actual building to it, guaranteed Cyberman (who far look better)/Weeping Angels/Daleks, two Doctors (one classic, one new) and a better looking TARDIS. Of course, with two projects both getting 10,000 LEGO will have to give in to the demand of LEGO Doctor Who. :)
Oh yes, another thing that is absolutely necessary is the TARDIS doors for the outside model; I can't imagine it being as fun without them.
