Free to play MMO for kids.
Neo 2045 is currently available on Steam in early access, but on September 23 you’ll be able to jump in and play it without the beta tag. The launch will include anticipated content like the Game Maker and pet battles. The game entered open beta earlier this year and advertises itself as child-friendly.
NEO 2045 is a sci-fi action MMO for all ages with a vast open world, loads of single and multiplayer mini-games accessible through various arenas and locations as well as a series of Social Realms and Player Realms where players can terraform mountains and valleys and build structures and vehicles using dynamorphic components that connect seamlessly.
