Which series would you like to see more of?

Seeing as someone already said Freespace (surprising, usually I'm the only one to say Freespace), Persona NEEDS SEQUELS!

On the subject of Persona, I am fairly certain that it was announced a while ago that Persona 5 was already in the works.
OT: The One Piece story games. I expect a new one about 5 years from now.
