There's one on PSX that I really loved that I can't remember the name of. There's like a secret agent character, a little girl who's a maid who fights using a broom, and a woman who uses kung fu. The game was in 3D. I think you were on a boat. Really wish I could remember the name of it.

I also really hate how a lot of these games remained arcade-only.
