Nice.
Just a wild idea:
It may be possible to design a simpler and fun! version of GO. For example,
design a simple cube or ball or pyramid or prism or diamond or graphite or
any suitable 3-D structures with certain coordinates. Design certain rules to
allow a player to remove the opponent's piece (in-between or outnumbered
on a line or within a closed loop/shape, etc.). Mix the game with shape
recognition or color recognition. Make the pieces larger so that it would
not be a health hazard for toddlers.
Sell the toy on Amazon or to pre-schools with concurrent educational website
created to help kids learn skills.
Then introduce the original GO when kids are older and get hooked by the
easier version of GO.
