The chao concept was ultimately underused, but they were a good sink of effort that gave you incentive to replay stages for the animals and upgrades.
The biggest missing feature was the ability to take them back out into the Adventure stages, like the PSOline mags. I feel that would make them a more complete addition to the game. Less a mostly disconnected mini-game but instead an integral part of the core gameplay.
We can dream but honestly when are we going to get the godlike SA1 controls. It's been over 20 years and every time I play a recent Sonic game it's like he moves by glitching. SA2 went in the wrong direction.
