Well, considering it was one of those unreleased prototypes that really only saw the light of day through showings at California Extreme until it was dumped and put in MAME... I really doubt most gamers know of its existence!
Theories as to why it wasn't released: Commenter "dauber" theorizes that "Vicious Circle" and other games' development was axed during the Midway/Atari Games merger for, uh, pure efficiency's sake (in the comments of the following page): https://www.kotaku.com.au/2016/04/lostbe...d-now-playable/
Brian McKee in the above Retrogaming Times article claimed it was "a COJAG based fighting game that could not get enough bandwidth from the hardware to be fun enough."
PS. Ironically, there's a character in the game named "Stiletta". No relation.
