ARMS imo is one of the weaker HD rumble titles. In fact, Shantae, Rabbids, TumbleSeed, MK8D, Graceful Explosion Machine, Thumper, Master Blaster Zero, and Overcooked all use HD rumble better than ARMS imo.

A real basic use of HD Rumble that developers seem to not really use it for is for menus. It adds a satisfying feel to just scrolling throught it. I personally believe HD rumble is totally worth it. Yet people have yet to experience games that use it really well like Shantae and just thinks its pretty much useless making developers seem to care less about it.

So aside from menu HD rumble here are some ideas of possible upcoming games and how it could use it.

Kirby for example can use the HD rumble when you suck up enemies, swallow enemies, and eject the power. It can also use the HD rumble to correspond with each power that you get, like with the fire power you can feel like which side you are breathing fire on or if its shooting high or low. Or the whip power where you can feel a satisfy "SNAP" everytime you use the whip. They can add HD rumble for swimming under water, and a very light rumble whenever you are dashing with kirby.

Another game that if it ever comes to switch can use HD Rumble is animal crossing. You could feel the HD rumble when fishing, digging, running(on different surfaces such as sand, grass, stone etc.), shooting the sling shot, throwing down decorations, moving decorations, even depositing money into the bank. Hell you could use the rumble to feel each individual footstep when sneaking up on a bug with a net and feel it when you swing the net and make contact with the tree and ground.

There are so many uses to HD rumble that i wish developers would look more into and try to incorporate more into their overall game because when its done well its really does add another layer to the game.
