If Sega could get off their ass and make any game with chao in it, or even just a standalone Chao Garden package game, they might actually jump out of their tar pit of suck
YESSSSSSSSSSSSSSSSSSSSSSSSSS
hopefully with not an entirely new engine, but like, a slightly modified version: you know, new animals, new chao, maybe a new statistic or two, VASTLY improved graphics...
if it's standalone, it could be made so that the longer you play the console the more animals and stuff you get- then, you can give them to your chao and make them better 'n stuff
