The Tiny Chao Garden is basically it's own game and even has it's own save inside the main save file of each game (deleting the save of a main game in it's options won't delete any progress in the TCG, which makes it impossible to reset it on real hardware without modifications).

Transferred from GCN Sonic Adventure 1/2 to GBA (though, those are not connected to another game and only exist until the GBA is turned off) So while the TCG is it's own game it is also connected in some way to the game it is included with. Because the special thing about the Tiny Chao Garden is that you automatically get all Rings you kept through a Level until the Goal of an Act in one of the main games. You only get a few Rings through the short minigames, so to acquire more Rings you have to get them another way. One minigame that is available in all TCG versions and one of four others that are available depending on what version of the TCG you use and what game it is included with. You can use Rings to buy Fruits and some Toys to make your Chao happy, which you can acquire through two minigames. The Tiny Chao Garden itself is basically a game inside a game, where you can raise and care for a small creature (a Chao) that you can then transfer to your GameCube copies of Sonic Adventure 1/2 or vice versa. I'm a big fan of the Sonic the Hedgehog Franchise and the Tiny Chao Garden game used in some GBA games of that series. This is a small series of some hypothetical questions and I hope it's alright for me to ask.
