Craig Stitt, former Sega Technical Institute artist, seems to have been digitizing some of his old VHS tapes lately. Among them was an old video resume from 1995 showing off art and game assets he made. Included were some concept screenshots for a pitch of a game called "Treasure Tails" from February 1993. It looks to be a sort of isometric puzzle-adventure game set in an ancient temple.
No other info is known about the game. Presumably it wasn't greenlit and no work went into making it an actually functioning game. But it makes you wonder what could have been, right?
