Even if this were to come to the United States, there isn't an arcade within 50 miles of me. So this game might as well not even exist.

Put it on the eShop please Nintendo.  That costs you almost nothing.

I would love for this to come out about 15 years ago...  I haven't seen a good arcade in a very long time, nor do I have buds that want to get together and go to arcades anymore.  Hopefully when my kids grow up this will be hip in the US again.

I played one of the Mario Kart arcade games once at some arcade in a mall, which was pretty much entirely imported Japanese arcade games and they all had gimmicks like steering wheels, lightguns, instrument controllers, etc.  It was just some game.  Like it wasn't bad but it wasn't noteworthy in any way.  I would never see myself paying to play it again.

Here in North America I figure an arcade Mario Kart would have been a huge deal in the 90's but today this is pretty much only of note for Japanese gamers.
