Wait on the inevitable "Sonic Adventure Collection", because I guarantee SEGA will remaster these games.

The physics are broken, sometimes you'll get launched in a random direction for no reason. Half your time is spent fighting the camera which has a mind of it's own. No real context to what is happening in the story, so it just feels like a bunch of levels thrown together.

You have to manually set your monitor to 60hz, otherwise the game will run too fast and become unplayable. Also, I had issues with mechanics being inconsistent, it's basically a 50/50 if a rail-grind or coin-dash will even work.

"I found you, FAKER!"
"Faker?! I think YOU'RE the fake hedgehog around here. You're comparing yourself to me? HA! You're not even good enough--"
"I'LL MAKE YOU EAT THOSE WORDS!"
"To be my fake."

Best series SEGA has made. We really all need a Adventure 3 with an expanded Chao world. The Chao should have more of a role in the game instead of a side quest. Either way I love the series and really wish they would continue it.
