No..... they really aren't. I'm not going to convince you otherwise, so I'm not going to try, other than say you're completely wrong. Sorry. This, on the other hand, I completely agree with. Make them their own Tamagotchi-style budget title, well away from the main proper games, and the diehard Chao fans who already own SA2 will buy it. Do it cheaply enough and sell at a high enough price and it'll make a net profit, shut the Chao-obsessers up, and fund some real Sonic titles at the same time.
