PR ideas?

I've been wanting to start a new RP so I might delete Real Ghost Stories
Here are some ideas that I would like your opinions on

Dinosaur King: Spin off from the TV series. A group of kids discovered mysterious stone slaps and dinosaur cards. When they rub the cards against the stones the cards into real live dinosaurs.
They are two groups; one group vows to collect all the dinosaur cards and bring the dinosaurs back home to their own time the other is an organization who wants to use the dinosaurs' powers for governmental or selfish purposes
Never played the game but I did watch the anime...most of it

Dinotopia: Spin off from the movie and books(?) There is a mysterious island unknown by the modern world where humans and dinosaurs coexists. Their paradise is protected by the outside world by the power of the sun stones. However castaways find their way to the island.
Two groups; you can either be a Dinotopia local or a Dolphinback; people who have stumbled upon the island by means of surviving a ship wreck or plane crash.
The OCs you must have are one human and their Lifemate a dinosaur
I think it'll be really cool. They're are talking dinosaurs! 8D

Cryptid Hunters: Go around the world to search from elusive and mysterious creatures of legend; Big Foot, lake monsters, sea monsters, the Yeti, Moth Man and more.
You know they're out there but can you find them?

Mystery Center: Spin off of Martin Mystery. You're an agent of the Center; a covert organization that works to protect the people of Earth from extraterrestrial and supernatural threats. You work as a team of three and with your trusty U Watch you solve paranormal mysteries
I think it would be cool
