This resulted in an even wider branching evolution system with over triple the amount of obtainable Chao evolutions. The player interactions were also changed, as playable characters were divided into two groups, Hero and Dark, which directly influence the Chao’s own alignment when shown affection.

The Chao Kindergarten was introduced, giving the player the Classroom to teach Chao special skills, the Principal to give advice about raising Chao, and a Doctor to check up on sick Chao. The sequel introduced the player to new gardens as well as an improved system for raising the Chao, cleaning up some glitches. This was also the only way to name the Chao and also the only way to look at the Chao’s attributes. Many prizes could be obtained on Chao Adventure that could be transferred back to the Chao Garden, as well as raising the Chao’s stats within the mini game itself. The game was accessed by placing the Chao in the VMU transfer machine found in each garden, and you would be able to play the game on the portable VMU away from the Dreamcast. There was also an exclusive mini-game called Chao Adventure that was played with the Visual Memory Unit (VMU). There were very few breeds of Chao, and the garden contained many inhospitable landscaping features. The Chao Garden had only a few- now standard, features: giving Chao fruits and animals, showing affection with each character, branching evolution based on skills, and racing. This was the first game to ever feature Chao, and thus had the most basic system compared to later games. Dreamcast Engine 1998: Sonic Adventure 1 (Dreamcast)

Let’s take a look at the timeline of the games and just how the Chao system developed. We can generally split the Chao systems up into two types - The Dreamcast games use the ‘ Dreamcast Engine’, and non-Dreamcast ( Modern) games, use the ‘ Gamecube Engine’. Since then, bother Sonic Adventure and Sonic Adventure 2 have been released, ported, and rebranded multiple times over many different formats. Chao have been present in the Sonic Adventure games since 1998 (Japan) on the Sega Dreamcast.
