Let me rephrase my opinion a bit, I think that the sets don't match the figs and that the big attack machines, like the one below, have been given to much of a Mars Mission twist. Just look at it, does that resemble something Ninja like to you?
The one above is just crazy looking, Ninjas don't fight skeletons on motorcycles! I just feel that the Lego Company could have made the theme/game a little more historical accurate. Rather than having a bike they could have had a battle cart etc.
That too.
