Pointer controls are a great fit for a third person rail shooter. The speed and accuracy of a pointer makes it a great fit for the genre. The Switch has two Joy-Con controllers, and as shown by games like Captain Toad, they can make pretty good pointing devices with their gyroscope. Since each Joy-Con has most of the same sensors, One idea that could be cool to see is a third person rail shooter with a dual gun aiming mechanic, where you have to aim and shoot two streams of fire independently throughout the level. Neonwall tried this concept somewhat, but I'm more so talking about something like Sin & Punishment with two guns you need to keep track of. The pointing functions of the Joy-Con aren't perfect though, unlike the Wii Remote, there's no IR reference point to rely on, it's all gyro, which means the cursor itself can go off-center occasionally. But they're a good enough replacement provided there's a recenter button and sensitivity settings.
