Motion control used to make you feel more "in the game" or for fitness and sports games ISN'T a gimmick.
3D used to give sense of depth and more immersion in the game and any other possible benefit to gameplay ISN'T a gimmick.
Force Feedback ISN'T a gimmick.
Rumble IS almost always a gimmick (the exception is when a rumble would actually be a proper feedback, for example driving on the gravel).
3D graphics popping out IS a gimmick.
... So 3D can be either good or gimmicky (and a game could even use it in both ways), it all depends on how it's used.
