Wow! Thanks for the information - had no idea about the patents. Nice to see Micky Albert crop up again!
Interesting about the IP sharing too. Surely a PC version could happen - but really, it would be perfect for the Switch. Especially in tabletop mode with the 3 Window mechanic.
I’d miss using A+B to pinch a replay Mii and drop it in though - Wii remote is still a sublime pointing device.
