Axie has a 100% player-owned, real money economy. Rather than selling game items or copies, the developers of the game focus on growing the player to player economy and take small fees to monetize. Axies are created by players using in-game resources (SLP & AXS) and sold to new/other players. You can think of Axie as a nation with a real economy. The holders of the AXS token are the government that receives tax revenues. The inventors/builders of the game, Sky Mavis, hold ~20% of all AXS tokens.
