#SonicAdventure was something else. I missed out on the #Saturn and its Sonic games, so it was my first next-gen #Sonic game. It had a wide variety of characters each with their own playstyles. Sonic goes fast, there was a robot (???) with a laser that did shooting stages, and... am I remembering going fishing with Big the Cat? I think I am. Good game that tried a lot of different things to various levels of success.
Oh! And the Chao minigame on the #Dreamcast VMUs. I don't think I ever gave that a go. Was it any good?
