The product decision behind it
Keep the rules everyone knows, then add one new idea at a time: bigger boards, a third player, powerups.
Every game in the studio starts the same way: decide who it's for, what the player does and what makes it fun. Then describe it to an AI, play it, and fix what the AI got wrong.
