Wow, the leg strap in Nintendo Switch Sports actually feels fairly immersive. Kicking with it feels fairly natural and HD rumble is even used effectively to make it feel like you've really hit the ball.
However, detection of if you have the strap ON is very finicky. In particular it seems unable to detect if you already have it on! Like they expect you to remove it after every game and put it back on if you play another game immediately. Or just to not play soccer repeatedly.
@noiob That's the thing, NSS seems to expect you'll ONLY put the strap on after selecting soccer (football okay) and then selecting to use the strap. It wouldn't detect that I already had it on, it wouldn't let me proceed until I took it off and then put it back on. Like it can only detect the process or something and doesn't expect me to be honest either.
