The Switch was playable at RTX so I have been able to get some impressions
1,2,Switch was actually good fun. Can see it being a regular ice breaker activity, at least with the games that work well.
New Controllers have got better Gyro's but the 'false positive' issues with motion controls in general aren't ironed out.
E.G. Arms has you move by tilting the controllers. Very sensitive, responsive, speed ties nicely to level of tilt. Swapping from forward to backward or vice versa quickly can register as throwing a punch. Leaving you open.
Table tennis in 1,2,Switch can sense you ending your return movement to be ready to swing as a swing & bone you.
Playing split screen on the tiny screen feels useless when you sit down to it but feels plenty big enough once playing. At least for Mario Kart so the portable screen is Don
Using just one of the tiny controllers for gaming goes the same way. Seems absolutely absurd, had no problems once I started racing. Explaining to people which button to press is going to be a nightmare if they already have trouble them though.
HD rumble is real. Totally sounded like a wank to me during the reveal in January. 1,2,Switch has a game where you need to guess how many balls are rolling around inside the controller (technically pretend the controller is a box) & I could not only reliably tell you how many but what corner they were hitting, when they hit each other, where in the box they were currently rolling. Heard of the compilation also including a safe cracking game done by means of the rumble & good reports of its accuracy.
Didn't use the IR sensor for the eating comp game. Everyone I saw had trouble though.
Can't say crap about battery life or use in tablet mode yet but all my impressions are favourable. Now all it needs is to show me software worth owning it to play
