Yes, legit, though somewhat down to earth (pun intended) Patlabor shown giant robots everywhere doing mundane job, and while not a giant franchise, it's far from unpopular. Hell, the titular mecha is armored with titanium-plastic-ceramic composite because the frame & actuator will be squeezed by heavier armor
Front mission also do just that, though their main focus still giant robot beating the crap out of each other.
