If it's supported in MarioKart it's nothing special. I don't think any of my other games use it.

I like it a lot actually, probably the best rumble I've felt in any video game controller.

I think it depends if you have good sensitivity in your hands, if your "touch challenged" then nothing will help

This game uses HD Rumble a lot (It's already out for $14.99 US, has recieved really good reviews)

I only have zelda and splatoon 2 I dont think any of them use it so I cant really say

Same here. It's nicer and more nuanced than regular rumble, but I wouldn't miss it if it was gone.

I only have MK8, not sure if it uses it. But if it does, I haven't noticed anything significant.

I found it most interesting in Shantae, Blaster Master, and 1 2 switch

Best use so far is in Blaster Master you can feel this accelerating feeling in the controller in one of the opening cinematics.

I've never been a big supporter of rumble in general and I typically just shut-off the feature to preserve battery. Though with WiiU and Switch pro-controllers having better battery life, I leave it on there. I did notice a difference between this and WiiU's rumble. I still don't consider rumble a must-have feature.

I honestly don't think we have a game that takes full advantage yet. Probably will be underutilized imo.

It will be used where it makes sense 

This game uses it to improve gameplay
